Abstract

The invention provides a method and a system for enabling antilock braking in a vehicle which is propelled at least by an electric motor. The method includes detecting tendency of locking of the at least one wheel by comparing actual rate of change of speed of the at least one of the motor, wheels, transmission, shaft and ground speed with expected rate of change of speed of at least one wheel, wherein the vehicle is being decelerated. Based on the tendency of locking at least regenerative braking is modulated to prevent locking of at least one wheel of the vehicle.

Description

technical field [0001] The present invention generally relates to a vehicle including an electric traction system. More specifically, the present invention relates to a method and system for decelerating a vehicle including an electric traction system. Background technique [0002] Typically, vehicles have mechanical brakes or hydraulic brakes, which are used to decelerate the vehicle. However, in the case of a vehicle with an electric traction system, such as an electric vehicle or a hybrid vehicle, in addition to using the existing mechanical brakes or hydraulic brakes in the vehicle to achieve deceleration, the vehicle also uses the propulsion system as the vehicle. motor to achieve deceleration. The use of electric motors to decelerate a vehicle is known in the art and is generally considered a type of regenerative braking. [0003] A brake device is one of the most crucial safety devices of a vehicle, and research has been conducted to overcome various problems relat...
