Electrical power assisted steering mechanism |
摘要 |
An electric power assisted steering mechanism for a automotive vehicle having a torque shaft interconnecting the vehicles steering wheel with the steering gear box. Electrical power is applied to the output end of the torque shaft by a low speed, high torque electrical motor through a low gear ratio planetary gear system disposed concentrically about the torque shaft. The electric motor is energized by a power amplifier in response to a torque signal generated by a torque sensor responsive to the magnitude and direction of the torque applied between the input and output ends of the torque shaft. The power amplifier has an anti-log gain characteristic eliminating the need for a vehicle speed input to reduce or eliminate the authority of the power steering mechanism a nominal and higher vehicle speeds.
