Abstract

The invention discloses a braking control method and system of a switching value braking pedal and further discloses a vehicle comprising the braking control system. The method comprises the steps that when a driver operates the braking pedal, the time duration of stamping on the braking pedal by the driver is obtained, and according to the time duration, the depth delta of the braking pedal is determined; the maximum permitted braking power of all parts of the current vehicle is obtained, and the minimum value in the maximum permitted braking power of all the parts is determined to the real-time maximum permitted braking power P<max>; and according to the depth delta of the braking pedal, the real-time maximum permitted braking power P<max> and the actual motor rotating speed, braking torque T<target> is obtained, and according to the depth delta of the braking pedal and the braking torque T<target>, the vehicle is controlled to be braked. According to the braking control method and system, the pedal braking behavior of a driver can be simulated, the braking intention of the driver is reflected, the reasonable braking torque distribution and vehicle safety of the vehicle are ensured, and the economical efficiency of the vehicle is ensured.

Description
