Title:
STEERING CONTROLLER AND ELECTRIC POWER VEHICLE
Document Type and Number:
WIPO Patent Application WO/2007/069763
Kind Code:
A1
Abstract:
Motor generators (IWMR, IWML) are assembled in front wheels (FR, FL) and drive
the front wheels (FR, FL). An ECU (36) judges whether or not any failure occurs
in a steering device comprising a steering actuator (28), tie rods (30), and a
steering angle sensor (32) on the basis of the operating angle (Δθs)
of a steering wheel (22) from a steering angle sensor (26) and the steering angle
(ΔD) of the front wheels (FR, FL) from the steering angle sensor (32). When
the ECU (36) judges that a failure occurs in the steering device, the ECU provides
a torque difference to the torque commands of the motor generators (IWMR, IWML)
according to the operating angle (Δθs) of the steering wheel (22).
