The Chinese company WM Motor has unveiled the M7 electric sedan concept. The car will receive three lidars with a total viewing angle of 330 degrees and almost 30 more sensors. The M7 will have a significant range for an electric car: 700 kilometers.
Lidars are a key sensor for self-driving cars. They send out laser beams and measure the time it takes for the light reflected from objects to reach the receiver. This allows you to accurately determine the distance to objects or even build a relief map of space.
A set of lidar, radar and other sensors can exceed the cost of the car itself, and some developers are creating self-driving cars without lidars. This is thanks in large part to the development of computer vision algorithms.
Tesla has only radars and cameras, and this year the company announced that it would even give up radars and use only cameras for navigation. The Chinese company WM Motor unveiled the M7 electric sedan concept on October 22.
The car received three lidars with a total viewing angle of 330 degrees, 5 millimeter-wave radars, 12 ultrasonic sensors, 7 cameras with a resolution of eight megapixels, 4 panoramic cameras and a high-precision positioning module.
Four NVIDIA DRIV Orin-X chips will process data from all these sensors. The computational capacity of each of them is 254 trillion operations per second. In addition to all kinds of sensors, the M7 is notable for its range, which exceeds 700 kilometers. Mass production and deliveries of the car are scheduled for 2022.
