Vehicle and vehicle collision protection method and system

The invention provides a vehicle and a vehicle collision protection method and system, and belongs to the field of vehicle collision safety. The method comprises the steps that the current value or the voltage value of an electronic type collision sensor within the vehicle collision triggering time is obtained, the average change rate of the current value or the voltage value within the vehicle collision triggering time is calculated, and the average change rate of the current value or the voltage value within the vehicle collision triggering time is compared with a set collision threshold value to determine the collision strength of a vehicle; braking control is conducted on the vehicle according to the determined collision strength, and collision protection of the vehicle is achieved. According to the method, the current or voltage values within the vehicle collision triggering time are continuously detected, the average change rate of the current or the voltage is calculated according to the multiple curre
