PURPOSE:To eliminate the need for the computation of respective input values by a computer and to reduce the cost by detecting acceleration and deceleration states by a change in the oil pressure of a hydraulic cylinder by the inertia force of a power unit generated at the time of acceleration and deceleration. CONSTITUTION:The power unit 3 consisting of a vertically placed engine 3a and a speed change gear 3b connected to the rear of the engine 3a, etc., is mounted in an engine room 2b in the front part of a vehicle body 2. This power unit 3 is mounted oscillatably via a cushion member 3c on the vehicle body 2 so that the oscillation of the power unit 3 is not transmitted to the body 2. Either of a piston rod 26 of a hydraulic cylinder 12 or cylinder body 13 is connected to the power unit 3, as well the other one is connected to the body 2. The piston rod 26 is extended or contracted by the inertia force of the power unit 3. The acceleration and deceleration are thereby detected by a change in the oil pressure. |
