CONTROL SYSTEM FOR HYBRID VEHICLE

A control system for a hybrid vehicle that can prevent an overcharging of a battery even if a wheel speed drops abruptly. The hybrid vehicle comprises: an engine; a generator that is driven by the engine; a drive motor that generate a drive torque; and a battery. The electric power generated by the generator is supplied directly to the battery or the drive motor. A controller is configured to determine whether the drive wheel will be locked, and to reduce the electric power generated by the generator less than an acceptable input power to the battery if the drive wheel is expected to be locked.
