Abstract

The invention relates to automotive electronic technology, in particular to a method and device for calibrating vehicle anti-collision parameters and a computer storage medium for implementing the method. The method for carrying out calibration to vehicle anti-collision parameters according to the present invention comprises the following steps: the standard value of the latest starting braking time TTAB and the latest standard value of starting turning time TTAS of the car are set; the calibration value and TTAS of determining TTAB and combining the standard value of TTAB and the standard value of TTAS with the respective calibration values ​​to determine the corrected value of TTAB and the corrected value of TTAS.

Description

technical field [0001] The invention relates to automotive electronic technology, in particular to a method and device for calibrating vehicle collision parameters and a computer storage medium for implementing the method. Background technique [0002] Automatic Emergency Braking (AEB) is used to avoid rear-end collisions or reduce injuries caused by rear-end collisions. A typical automatic braking system generates the timing of the braking command in the following way: determine the time to collision (TTC) of the vehicle relative to the vehicle in front according to the speed and distance of the vehicle in front Time (TTAB) is compared, if TTC is less than TTAB, it indicates that the AEB system must immediately perform a braking operation to avoid a collision. [0003] However, due to the existence of individual differences, it is not appropriate to use the same standard TTAB for all users. Therefore, there is a need for an automatic calibration method and device to adapt...
