Abstract
A driving assistance system for a work vehicle may comprise a service brake configured to decelerate the work vehicle upon actuation of the service brake, a parking brake and a transmission including a clutch. A controller may be configured to disengage the clutch when the work vehicle speed is less than a speed threshold and when the service brake is actuated, whereby the work vehicle is brought to a stop.
Claims20
A driving assistance system for a work vehicle comprising a service brake configured to decelerate the work vehicle upon actuation of the service brake, a parking brake and a transmission including a clutch, the driving assistance system comprising a controller configured to:
- disengage the clutch when the work vehicle speed is less than a speed threshold and the service brake is actuated, whereby the work vehicle is brought to a stop;
- obtain a slope value representative of a slope of a surface on which the work vehicle has stopped;
- automatically activate the parking brake when the clutch has been disengaged and the slope value is greater than a slope threshold;
- reengage the clutch when the service brake is released, while maintaining the parking brake activated;
- and
- automatically deactivate the parking brake when a predetermined delay after release of the service brake has elapsed, the predetermined delay being greater than the time required to reengage the clutch, or when reengagement of the clutch has reached a predetermined value.
A driving assistance method for a work vehicle comprising a service brake configured to decelerate the work vehicle upon actuation of the service brake, a parking brake and a transmission including a clutch, the driving assistance method comprising:
- disengaging the clutch when the work vehicle speed is less than a speed threshold and the service brake is actuated, whereby the work vehicle is brought to a stop;
- obtaining a slope value representative of a slope of a surface on which the work vehicle has stopped;
- automatically activating the parking brake when the clutch has been disengaged and the slope value is greater than a slope threshold;
- reengaging the clutch when the service brake is released, while maintaining the parking brake activated;
- and
- automatically deactivating the parking brake when a predetermined delay after release of the service brake has elapsed, the predetermined delay being greater than the time required to reengage the clutch, or when reengagement of the clutch has reached a predetermined value.
