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 &#x394;T applied to the left and right wheels during cornering, left and right torque-difference maintaining torques TLand TRof the motors when generating the demand torque Tr while maintaining the torque difference &#x394;T, and controls the motors based on the torque-difference maintaining torques TLand TR. 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 &#x394;T depending on the driving operation detected by the detector.

Driving attentiveness judging method and apparatus for accurately determining the driver's attentiveness level during driving of a motor vehicle are provided wherein steering angle data and vehicle speed data, respectively supplied from a steering angle sensor and a vehicle speed sensor, are sampled by a steering angle data sampling section and a vehicle speed data sampling section, respectively. Respective levels of road shape component, visual steering component, and corrective steering component of the steering angle data are detected by a steering angle data processing section, and a fuzzy inference output representing a driving attentiveness level is obtained by a fuzzy inference section in accordance with fuzzy rules and the three steering component levels. In accordance with the fuzzy inference output which has been subjected to vehicle speed-dependent correction by a vehicle speed correcting section, the driving attentiveness level is displayed at a display device, and also a warning mark is displayed if the vehicle speed-corrected fuzzy inference output is small.
