CONTROL SYSTEM AND METHOD FOR IMPROVING VEHICLE TURNING PERFORMANCE

摘要

A control system for a motor vehicle that operates to receive a signal indicative of a steering angle of a vehicle and cause application of negative torque to one or more wheels of a vehicle to slow a wheel. The system is configured to perform a turn-assist operation in which the system causes application of negative torque to at least a first wheel of a vehicle being an inside trailing wheel when a steering angle exceeds a predetermined steering angle thereby to promote turning of a vehicle. The amount of negative torque is arranged to increase with increasing steering angle beyond the predetermined steering angle.

主权项

1. A control system for a motor vehicle comprising:
means for receiving a signal indicative of a steering angle of a vehicle; and means for causing application of negative torque to one or more wheels of a vehicle to slow a wheel, the system being configured to perform a turn-assist operation in which the system causes application of negative torque to at least a first wheel of a vehicle being an inside trailing wheel when a steering angle exceeds a predetermined steering angle thereby to promote turning of a vehicle, the amount of negative torque being arranged to increase with increasing steering angle beyond the predetermined steering angle, the system comprising means for causing application of positive drive torque to one or more wheels of a vehicle, the system being configured to cause an increase in an amount of net torque applied to at least a second wheel of a vehicle to compensate for application of negative torque to at least a first wheel when a turn-assist operation is in progress.
