摘要：A driver state estimation device includes a steering angle sensor detecting asteering angle of a steering, a steering torque sensor detecting steering torque appliedto the steering, and an ECU having a steering angle estimation unit and a driver stateestimation unit . The steering angle estimation unit is input with a steering angle (steering
angle detected value) MA detected by the steering angle sensor and steering torque(steering torque detected value) MT detected by the steering torque sensor ,
determines whether the steering angle detected value MA is 0 or not, when the steeringangle detected value MA is 0, calculates a steering angle estimated value MAest bymultiplying the steering torque detected value MT by the gradient of the steering angle(proportionality coefficient) α with respect to the steering torque, and when the steeringangle detected value MA is not 0, sets the steering angle detected value MA as thesteering angle estimated value MAest.
