PURPOSE:To properly operate sufficient deceleration when a running load following steering operation is increased by performing decelerating operation through a velocity control means at a velocity larger than in a non-steering operation at the time of steering operation, based on the information of a steering condition detecting means. CONSTITUTION:At the time of deceleration, whether a working vehicle is turning or not is judged by a controller 100 (velocity control means), based on the information of a sensor S2 for detecting steering condition. When it is turning, deceleration is performed at a larger decelerating velocity that in a non-turning mode. An electric motor 8 is intermittently driven, so as to change decelerating velocity. Output timing and a cycle for output are to be determined for intermittent driving of the motor 8, for which a cycle during non-steering is also made smaller than a cycle t' or steering, however, by making an output timing T during non-steering sufficiently larger than an output timing T' during steering, decelerating velocity during steering is defined larger than in a non-steering mode. |
