AI Technical Summary
The prior art has low accuracy in calculating vehicle speed when driving at low speed, which affects the handling accuracy of automatic parking and advanced assisted driving systems, and there is a time accumulation error in the vehicle speed calculated by motor rotation information.
By receiving the synchronization signal of the upper computer controller, the rotation information and time information of the motor are obtained after synchronous timing, and sent it to the upper computer controller to calculate the vehicle speed based on this information.
It avoids cumulative errors in vehicle speed calculation, improves the accuracy and accuracy of vehicle speed calculation, especially at low speed situations, which can provide high-precision vehicle speed data, and improves parking control and panoramic splicing effects.
