Abstract
A system and method are provided for controlling a drivetrain of a vehicle which includes a prime mover operatively connected to at least one tractive element. The system and method include determining the vehicle's total weight and, using an electronic controller carried by the vehicle, causing the prime mover to apply power to the tractive element so as to propel the vehicle. The magnitude of the power can be a function of the vehicle's total weight.
Claims20
A method comprising:
- applying a retarding force to a tractive element of a vehicle, the retarding force limited to no greater than a predetermined baseline retarding force;
- responsive to the speed of the vehicle exceeding one or more boundaries of a retard envelope, applying an increased retarding force to the tractive element;
- and
- responsive to the speed of the vehicle being within the boundaries of the retard envelope, reducing the retarding force that is applied to the tractive element to the baseline retarding force.
1 more element
A system comprising:
- an electronic controller configured to be operably connected to a traction motor of a vehicle, the controller configured to determine a total weight of the vehicle and to direct a traction motor of the vehicle to apply power to a tractive element of the vehicle so as to propel the vehicle, wherein the controller is configured to control the traction motor such that a magnitude of the power that is applied is proportional to the total weight of the vehicle.
A system comprising:
- an electronic controller configured to be operably connected to a traction motor of a vehicle, the controller configured to determine a weight of the vehicle and to direct a fraction motor of the vehicle to apply power to a tractive element of the vehicle so as to propel the vehicle, wherein the controller is configured to control the traction motor such that a magnitude of the power that is applied is proportional to the total weight of the vehicle, the controller further configured to direct the traction motor to apply a predetermined baseline retarding force to the tractive element and to determine a speed of the vehicle with reference to a retard envelope,
- wherein the controller also is configured to, responsive to the speed of the vehicle exceeding one or more boundaries of the retard envelope, direct the traction motor to apply an increased retarding force to the tractive element and, responsive to the speed of the vehicle returning to within the one or more boundaries of the retard envelope, direct the traction motor to reduce the retarding force to the baseline retarding force.
