Title:
流体圧アシスト車両の制御装置
Document Type and Number:
Japanese Patent JP5792148
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a control apparatus for a hydrostatic pressure assist vehicle which is equipped with a hydrostatic pressure assist mechanism and outputs a deceleration request torque which an operator requests at the time of deceleration thereby improving drivability.SOLUTION: An apparatus equipped with a pump/motor and an accumulator which are connected to a vehicle-loaded engine, in which the pump/motor is driven as a pump to discharge a fluid pressure thereby performing hydraulic regeneration (regeneration of a deceleration energy) in the accumulator when a vehicle is decelerated, and the pump/motor is driven as a motor when the vehicle is started and so on, whereby drive of the engine is assisted by an accumulated fluid pressure. In the apparatus, a deceleration request torque which an operator requests is calculated on the basis of a brake fluid pressure and a vehicle speed (S10), a target value of a fluid pressure to be outputted by the pump/motor on the basis of the calculated deceleration request torque and the revolution speed of the pump/motor (S14), and feed back control for a supply current to a solenoid selector valve is so carried out that the fluid pressure to be outputted by the pump/motor becomes the target value (S16, S18).
