  • Patent number: 9403446
    Abstract: A driving-force controller for an electric vehicle including at least two motors that independently drive left and right wheels, includes a detector that detects driving operation by a driver, and a controller that calculates a demand torque Tr of the driver, the torque difference ?T applied to the left and right wheels during cornering, left and right torque-difference maintaining torques TLK and TRK of the motors when generating the demand torque Tr while maintaining the torque difference ?T, and controls the motors based on the torque-difference maintaining torques TLK and TRK. The controller determines the priorities of a demand torque mode that generates the demand torque Tr and a torque difference mode that generates the torque difference ?T depending on the driving operation detected by the detector.

  • Patent number: 9266466
    Abstract: A stop lamp lighting control device for an electric vehicle having an electric regenerative braking system, includes, a first calculation unit that converts a first deceleration threshold value to a first regenerative torque threshold value with a curb weight, a second calculation unit that converting a second deceleration threshold value to a second regenerative torque threshold value with a gross vehicle weight, a third calculation unit that calculates a third regenerative torque threshold value, and a determination unit that controls the stop lamp to be turned on when a regenerative torque value exceeds the first regenerative torque threshold value, the stop lamp to be turned off when the regenerative torque value is equal to or smaller than the second regenerative torque threshold value, and the stop lamp to be turned off when a given state continues.

  • Patent number: 9266467
    Abstract: A stop lamp lighting control device for an electric vehicle having an electric regenerative braking system includes a calculation unit that converts a first deceleration threshold value for turning on a stop lamp or a second deceleration threshold value for turning off the stop lamp to a first regenerative torque threshold value for turning-on the stop lamp or a second regenerative torque threshold value for turning-off the stop lamp by calculation assumed that a weight of the vehicle is a curb weight or a gross vehicle weight, and a determination unit that performs a comparison between a regenerative torque value generated by the electric regenerative braking system and the first regenerative torque threshold value or the second regenerative torque threshold value and controls the stop lamp to be turned on or turned off based on the comparison result.
