Abstract
A vehicle steering control system that controls the operation of an electric vehicle steering device, which applies a steering assist force to a steering mechanism via a gear mechanism and includes: a temperature estimating section for estimating the temperature of or around the gear mechanism; and a correcting section for correcting the steering assist force according to the estimated gear temperature.
Claims26
A vehicle steering control system for controlling operation of an electric vehicle steering device which applies a steering assist force to a steering mechanism via a gear mechanism, comprising:
- a temperature estimating section for estimating a gear temperature as a temperature of the gear mechanism or around the gear mechanism;
- and
- a correcting section for correcting the steering assist force according to the estimated gear temperature.
A method for controlling a vehicle steering control system for controlling operation of an electric vehicle steering device, which applies a steering assist force to a steering mechanism via a gear mechanism, comprising:
- estimating a gear temperature as a temperature of or around the gear mechanism;
- and
- correcting the steering assist force according to the estimated gear temperature.
A vehicle steering control system for controlling operation of an electric vehicle steering device which applies a steering assist force to a steering mechanism via a gear mechanism, comprising:
- a temperature estimating section for estimating a gear temperature as a temperature of the gear mechanism or around the gear mechanism based on a difference between a temperature of a control unit that controls the operation of the vehicle steering device and an ambient temperature;
- and
- a correcting section for correcting the steering assist force according to the estimated gear temperature.
