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.
Claims23
A control system for a vehicle having a sensor adapted to indicate wading above a pre-determined depth of water, said control system being adapted to implement one or more control strategies upon detection of wading by said sensor, said control strategies being selected from the group comprising:
- change of traction mode;
- change of throttle mapping;
- change of gear selection mode;
- change of high/low range mode;
- activate headlights;
- select higher air intake path;
- adapt tire pressures to wading;
- change steering response/feel;
- change differential control;
- change torque-vectoring control;
- change hybrid vehicle drive mode;
- activate heating, ventilation and air conditioning system (HVAC);
- delay regeneration of exhaust particle filter;
- partially flood a pre-determined portion of the vehicle;
- unlock door locks;
- open sun roof;
- activate hydraulic lock sensor of engine;
- and
- deactivate fuel saving mode
(canceled)
A control system for a vehicle having a wading sensor adapted to indicate wading above a pre-determined depth of water, said control system being adapted to implement one or more vehicle control strategies upon detection of wading by said sensor, said strategies being selected from:
- activate hydraulic lock sensor of engine, and
- de-activate engine fuel saving mode.
A vehicle comprising a control system and having a sensor adapted to indicate wading above a predetermined depth of water, the control system being adapted to implement a change in one or more vehicle control strategies upon detection of wading by said sensor.
A method for a vehicle comprising determining that the vehicle is wading and implementing one or more control strategies in response to determining that the vehicle is wading, said control strategies being selected from:
- change of traction mode;
- change of throttle mapping;
- change of gear selection mode;
- change of high/low range mode;
- activate headlights;
- select higher air intake path;
- adapt tire pressures to wading;
- change steering response/feel;
- change differential control;
- change torque-vectoring control;
- change hybrid vehicle drive mode;
- activate heating, ventilation and air conditioning system (HVAC);
- delay regeneration of exhaust particle filter;
- partially flood a pre-determined portion of the vehicle;
- unlock door locks;
- open sun roof;
- activate hydraulic lock sensor of engine, and
- de-activate engine fuel saving mode.
