Abstract

The invention discloses a motor type active stable rod control system. The system comprises a transverse acceleration sensor (1), a roll velocity sensor (2), a wheel speed sensor (3), a steering angle sensor (4), a dip angle sensor (5), a yaw velocity sensor (6), an ECU control unit (7), a driving circuit (8) and an executing mechanism (9). The ECU control unit (7) is electrically connected with the executing mechanism (9) through the driving circuit (8), and the transverse acceleration sensor (1), the roll velocity sensor (2), the wheel speed sensor (3), the steering angle sensor (4), the dip angle sensor (5) and the yaw velocity sensor (6) are electrically connected with the ECU control unit (7). The motor type active stable rod control system can select reasonable work modes according to different running conditions of a vehicle, a required rolling moment resistant torque value is adjusted in real time, and rolling of a vehicle body is effectively inhibited.

Description

technical field [0001] The invention belongs to the technical field of electronic control for vehicle running safety, in particular to a motor-type active stabilizer bar control system with low cost and which can take into account various working conditions of vehicle running. Background technique [0002] Most of the existing automobile stabilizer bars adopt passive stabilizer bars. This passive stabilizer bar is only designed for the working condition when the vehicle rolls. The structure is fixed and single, and the stiffness cannot be adjusted. When the vehicle is running on a smooth road, it is easy to cause the suspension stiffness to be too large, and it is impossible to take into account both ride comfort and handling stability. For this reason, an active stabilizer bar has been improved on this basis. The active stabilizer bar can adjust the anti-roll moment value at both ends of the stabilizer bar in real time according to the different roll degrees of the vehicl...
