I don’t know what Meng Jianqi’s plan is. They were waiting at the recycling bin. Meng Jianqi pointed to several cars in the empty parking lot. One of them has a rather peculiar shape. He asked: "Is this your battery car?"
Yonghan said: "Yes. There was an electric car competition, and the company gave them to some employees. The company also participated in the design of this electric car."
That time the company held an electric vehicle competition on a figure track. This competition is set up on some very narrow tracks. It is necessary to make full use of the advantages of new electric vehicles. For example, the wheels can rotate 360 degrees, they can quickly change from backward to forward, and they can drive directly left or right to move out of the parking space. There is a take-off board under the car, which can be propped down to allow the car to leave the ground and jump up a short distance.
Each person is assigned a car, and the maintenance and repairs of the car need to be handled by themselves.
Yonghan and Qufei signed up to participate. Yonghan asked: "Can you drive?"
Qu Fei said: "Of course. I often participate in vehicle testing."
How was your car's maintenance? I'll take another look. "
"Safety first. Fortunately, there is nothing wrong."
After playing at the practice venue for a while, Yonghan discovered that her level was no less than his own.
At the beginning of this competition, Yonghan didn't have much hope. But later I found that the points in the points competition were not bad, and I could make a push and enter the finals.
Yonghan took a closer look and saw that the car also had an inertial navigation system. That is, the inertial element-accelerometer can be used to measure the acceleration of the vehicle itself, and the speed and position can be obtained through integration and calculation, thereby achieving the purpose of navigation and positioning of the vehicle. The equipment that makes up the inertial navigation system is installed in the carrier. When working, it does not rely on external information, does not radiate energy to the outside world, and is not susceptible to interference. It is an autonomous navigation system. Inertial navigation systems usually consist of inertial measurement devices, computers, control displays, etc. Inertial measurement devices include accelerometers and gyroscopes, also known as inertial measurement units. The three-degree-of-freedom gyroscope is used to measure the three rotational motions of the carrier; the three accelerometers are used to measure the acceleration of the three translational motions of the carrier. The computer calculates the speed and position data of the carrier based on the measured acceleration signal.
Dai Yuchi, Shi Qiubing, Jiang Xunyi, Qu Fei, and Yonghan ranked higher in total points in several rounds of points competition and entered the finals. Dai Yuchi and Shi Qiubing are electrical majors. Jiang Xunyi is a computer major.
There are sharp turning areas on the track, uphill and downhill slopes, several 90-degree turning areas, and several parking spaces and garages. Parking into parking spaces or warehousing tasks can increase points. There is a flying car section, and there is a take-off board under the car, which can be pushed downwards, allowing the car to leave the ground and take off a short distance upward. Since the car will receive a lot of force when it lands, there is a shock-absorbing device below the landing point. Unlike in the movies, where a flying car can land unscathed, the flying car falls to the ground with great force, which is similar to driving a car into a wall. It can even cause the airbag to deploy and even injure the driver.
Game start. The electric car travels on the track at a speed of nearly 60 miles per hour. Yonghan concentrated on driving, paying attention in advance when turning every corner. The narrow track is like a flowing ribbon. Running out of the track means deducting a lot of points. At first, I saw Qu Fei at a nearby track. After a while, I focused on driving, and I didn’t know where she drove.
Dai Yuchi, Shi Qiubing, and Jiang Xunyi are all veteran drivers. Dai Yuchi drove flexibly and entered many parking spaces, earning points. However, Yonghan often squeezed into the parking spaces in front of him, making it impossible for him to enter.
Shi Qiubing is good at jumping on the speed board and takes the speed lane, which is similar to Yonghan's progress.
Jiang Xunyi is the fastest runner. A one second lead is worth 10 points, and occupying a parking space is worth 100 points. Sometimes there is a trade-off. If you can occupy a parking space within 10 seconds, occupy it, otherwise give up. One speeding trip costs 150 points. If you can complete the speeding action within 15 seconds, take this lane.
The road ahead is increasingly complex. There are mountains blocking the area, and the satellite signal is intermittent.
Jiang Xunyi turned on the satellite positioning system and saw that it was always waiting to receive signals. It was still like this after more than ten minutes of driving. If the signal is not good, there is no need to use the positioning system. You can only make your own judgment by looking at the road.
Yonghan turned on the inertial navigation system in advance. Look at the map to see where your car is on the map and where the end point is approximately. Everyone started from the south and finally reached the end point in the north through some tunnels. Some are from the west, and some are from the east.
There were many tasks. After completing one task and then rushing to the next task point, Yonghan felt very tired. Although the air conditioner was turned on in the car, I was still sweating.
When we first came out of the tunnel, some mud slid down the mountain, probably due to the rain some time ago, and some relatively large mud pits appeared here. Dai Yuchi's car got stuck in the mud and couldn't get out no matter how hard it started. The wheels were just spinning, leaving the mud and water behind. The key is that there is still a lot of water in the mud on the mountain. Then the mud and water on the mountain will slide down, putting the car in a very dangerous situation. If the dirt continues to slide, it could cover the car under the dirt or run off the road.
Qu Fei had stopped, found a chain and tied it to the front of Dai Yuchi's car. Yonghan also quickly turned around, took out a chain and tied it to the front of the car. They used full power to drag Dai Yuchi's car out of the mud pit.
Qu Fei said: "Why did you switch back? It's delaying your game."
Yonghan said: "You have stopped, why don't I come over and take a look?"
The game is important, but he has always believed that there are many things more important than scores. Doing something real is better than empty honor.
Yonghan would rather let them all go and leave this dangerous place first. "It doesn't matter to me, you go first. I can solve these things." He always thought like this unconsciously.
Qu Fei, Yong Han, and Dai Yuchi's cars started to start again and continued the race.
Shi Qiu Bingfei made a mistake while driving, causing small damage to the front of the car, causing the car to slow down.
Yong Han and Jiang Xunyi drove side by side. There was a small parking space next to it, but the location was too far away. Yong Han rushed over to occupy it, and then immediately reversed the car. Using the characteristics of the wheels, he instantly reversed and turned forward, following Jiang Xunyi. At this time, he encountered Qu Fei coming from another lane and chased after him.
We are almost at the finish line, and there are three parking spaces side by side. We need to get in first and then quickly turn around and cross the line.
Jiang Xunyi and Qu Fei rushed into the parking spaces on both sides. Yonghan slowed down and reversed the car.
After occupying the position, you need to drive out and sprint to the finish line. Yonghan could rush out in the forward direction at this time, while Jiang Xunyi and Qu Fei could only reverse out. Moreover, the track was very narrow and there was no way to turn around. If they walked side by side for a while, the reverse speed would be slower after all. Yonghan gradually took the lead and sprinted to the finish line.
In the end, Yonghan won, and the prize was a DS electric car produced by the company. Several other colleagues who entered the finals also received DL electric cars. Yonghan can use this electric car as his daily transportation to the maintenance site.
