Title:
電気自動車及び自動車用ヒルホールド方法
Document Type and Number:
Japanese Patent JP4272734
Kind Code:
B2
Abstract:
A hill-holding arrangement for an electrically driven vehicle includes a vehicle with a "gas pedal" which generates a torque command signal TCMD. A switch (314) couples TCMD to a motor controller (316, 14) which drives the motor (40) and therefore the vehicle. When the "gas pedal" calls for zero torque, and the vehicle speed is zero, the switch responds to logic (FIGURE 5), and substitutes a position-holding torque command signal Tθ for the operator-controlled torque command signal TCMD. Position controlling torque command Tθ is generated by a controller (312) which receives a position signal representative of the angular position θ of the rotor. The position-holding torque control loop then produces such torque as may be required to prevent the rotor of the motor from moving from its commanded position.
