System and method for driving and braking torque control in electric vehicles with independent wheel drive

摘要

Drive and braking torque control system in electric vehicles with independent wheel drive; comprising: - a storage unit (117) for charging or discharging with electrical energy; - For each driven wheel (101-104) each having an electric motor (105-108), each of which generates a driving or braking torque on the wheel (101-104); - Sensor units (118-125) for detecting the state of the memory unit (117), the position of a driving or brake pedal (128, 129), the rotational speeds of the individual wheels (101-104) and the acceleration of the vehicle body (130) in the direction of travel ; and - a unit for regulating the driving and braking torques (127) on each individual wheel (101-104); characterized by further comprising a brake control unit (126) for generating a friction braking torque by means of a friction brake (113-116) on the respective wheel (101-104); and that said drive and brake torque control unit (127) has a demand torque generating unit (201), a reference slip generation unit (202), a reaction torque control unit (203), a slip detection unit and driving speed (207) and a unit for determining a corrected driving or braking torque (204).
