Problems solved by technology
The shortcomings of radar speed measurement are: it is difficult to measure stereo sound, and due to the limitation of the number of sensors, the data collection is not flexible enough, the algorithm accuracy is not enough, and there are large errors
However, the current distance measurement method is based on the calculation of the number of rotations of the wheels. The calculated distance has errors and the accuracy is not enough.

The present invention discloses a measurement system of motor vehicle motion performance and a measurement method thereof. The system comprises a falling ball device, a photoelectric sensor and a control mechanism. The falling ball device comprises a first falling ball mechanism and a second falling ball mechanism. The first falling ball mechanism and the second falling ball mechanism are respectively provided with a first falling ball position and a second falling ball position. Balls are placed on the first falling ball position and the second falling ball position. The first falling ball mechanism allows the ball on the first falling ball position to fall, and the second falling ball mechanism allows the ball on the second falling ball position to fall. The photoelectric sensor is under the falling ball positions and is used for obtaining the position information when the balls fall to the plane where the photoelectric sensor is. The control mechanism is electrically connected to the first falling ball mechanism, the second falling ball mechanism and the photoelectric sensor. According to the system and the method, the traveling speed and traveling distance of a motor vehicle can be accurately obtained.
Description
technical field [0001] The invention relates to the technical field of measuring vehicle speed and driving distance, in particular to a system and method for measuring the motion performance of a motor vehicle. Background technique [0002] At present, the measurement methods of vehicle speed are mainly artificial judgment of vehicle speed based on experience, speed measurement based on video technology and radar speed measurement. The speed of the vehicle is judged artificially based on experience: after a period of training, the traffic police can obtain the speed of the vehicle by listening to the sound in the same place. However, human judgment of vehicle speed inevitably has empiricism and certain errors. The speed measurement based on video technology is: take two photos continuously, and obtain the vehicle speed according to the displacement of the objects in the two photos. The test method based on video technology has a large error due to the short time, the short...
