| 发明名称 | Vehicle control system and method to provide desired wheel slip | ||
| 摘要 | The invention relates to a control system and methods for controlling motion of a vehicle over a surface. The control system limits an amount of drive torque that may be applied to one or more wheels of the vehicle to prevent an amount of wheel slip from exceeding a prescribed value. The prescribed value of wheel slip is determined in dependence at least in part on vehicle speed. In addition, method claims 28 and 29 are directed to providing drive torque, independent of vehicle speed, which corresponds to or exceeds the maximum traction force. These methods are suitable for highway driving with high friction or off road driving on soft terrain, respectively. | ||

| 主权项 | 1. A control system that controls motion of a vehicle over a surface, the control system being operable to limit an amount of drive torque that may be applied to one or more wheels of the vehicle that are arranged to be driven to a prescribed torque value so as to prevent an amount of wheel slip from exceeding a prescribed value of wheel slip, wherein the prescribed value of wheel slip is determined in dependence at least in part on vehicle speed, and wherein the control system is operable to increase applied drive torque at a rate of increase, said rate limited to a prescribed maximum value, as the value of applied drive torque increases toward the prescribed torque value. | ||
