Title:
ACCUMULATING BRAKING ENERGY REGENERATION DEVICE OF VEHICLE
Document Type and Number:
Japanese Patent JP3158235
Kind Code:
B2
Abstract:
PURPOSE: To enhance the reductive effect of nitrogen oxides (NOx) as well as to improve the drivability by making car tractive force constant irrespective of the presence of regenerative power.
CONSTITUTION: At the time of regerative power outputting, a slash command of engine torque is imparted to a control unit 60 from another control unit 61. At this time, the control unit 60 increases a slash value of engine total load torque, insomuch that speed is higher, according to a gear position of a transmission. The slash value of the engine total load torque at each shift speed is performed of its maximum output point as far as an engine torque portion equivalent to the regenerative power in time of minimum pressure accumulation in an accumulator. In addition, an engine total load torque slash value is almost kept constant irrespective engine speed, or it is made larger in proportion as going to an engine high speed range. With this, a reductive effect of NOx is enhanced while drivability is made improvable.
