Abstract
A vehicle having a wading sensor may include a control unit adapted to implement an alternative or modified vehicle control strategy during wading. The wading strategy may change many vehicle functions, alone or in combination, and may be further responsive to depth of wading.
Claims17
A land based vehicle comprising a control system for aiding control of the vehicle when the vehicle is wading, the vehicle having a sensor adapted to indicate that the vehicle is wading in water having a depth above a pre-determined depth of water, said control system being configured to automatically implement one or more control strategies in dependence upon detection by the sensor of wading of the vehicle in water having a depth above the pre-determined depth to aid in the control of the vehicle when the vehicle is wading, said vehicle control strategies being selected from a group consisting of:
- change of traction mode;
- change of throttle mapping;
- change of high/low range mode;
- change steering response/feel;
- change differential control for improving traction;
- change torque-vectoring control;
- delay regeneration of exhaust particle filter;
- and
- partially flood a pre-determined portion of the vehicle.
A control system for a vehicle for aiding control of the vehicle when the vehicle is wading in water having a depth above a pre-determined depth of water, said control system being configured to automatically implement one or more vehicle control strategies in dependence upon detection of wading of the vehicle in water having a depth above the pre-determined depth by a wading sensor of the vehicle, said vehicle control strategies being selected from a group consisting of:
- change of traction mode;
- change of throttle mapping;
- change of high/low range mode;
- change steering response/feel;
- change differential control for improving traction;
- change torque-vectoring control;
- delay regeneration of exhaust particle filter;
- and
- partially flood a pre-determined portion of the vehicle.
A method for aiding control of a wading vehicle comprising:
- receiving data from a sensor adapted to indicate evading of the vehicle in water having a depth above a pre-determined depth, of water;
- determining that the vehicle is wading in water having a depth above the pre-determined depth;
- and automatically implementing one or more control strategies in response to determining that the vehicle is wading in water having a depth above the pre-determined depth, said one or more vehicle control strategies being selected from a group consisting of:
- change of traction mode;
- change of throttle mapping;
- change of high/low range mode;
- change steering response/feel;
- change differential control;
- change torque-vectoring control;
- delay regeneration of exhaust particle filter;
- and
- partially flood a pre-determined portion of the vehicle.
