Abstract
A system and method for braking a towed conveyance. In one embodiment, a system is provided for use on a trailer (102) having an axle assembly (108). The system (100) includes a motor controller (124), a pair of electric motor/generators (120), a battery (122), a battery controller (126), and sensors (128). Controller (124) monitors the yaw rate of trailer (102) by use of sensors (128). Based upon the monitored yaw rate, controller (124) selectively activates motor/generators (120) which provide a regenerative braking torque to axle assembly (108), thereby braking trailer (102) and generating electrical energy which may be used to recharge battery (122).
Claims17
A method for towing a first automobile by the use of a second automobile wherein said first and said second automobiles each being of the type having a braking system and a controller which is coupled to said braking system, said method comprising:
- generating a brake request signal in said second automobile;
- communicating said generated brake request signal to said controller which is resident within said second automobile;
- causing said controller within said second automobile to activate said braking system of said second automobile upon receipt of said brake request signal, thereby braking said second automobile by a certain first amount;
- causing said controller of said second automobile to generate a brake request signal to said controller of said first automobile;
- causing said controller of said first automobile to activate said braking system of said first automobile upon receipt of said brake request signal emanating from said controller of said second automobile, thereby braking said first automobile by a certain second amount which is less than said first amount, thereby causing said braking system of said first automobile to augment said braking system of said second automobile by supplementing the amount of braking provided by said braking system of said first automobile.
A method for towing a first automobile by the use of a second automobile wherein said first and said second automobiles each being of the type having at least one driver operated assembly and a controller which is coupled to said at least one driver operated assembly, said method comprising:
- generating a driver operated control signal in said second automobile;
- communicating said generated driver operated control signal to said controller which is resident within said first automobile;
- causing said controller within said second automobile to activate said at least one driver operated assembly within said second automobile upon receipt of said driver operated control signal;
- causing said controller of said second automobile to generate a driver operated control request signal to said controller of said first automobile;
- and
- causing said controller of said first automobile to activate said at least one driver operated assembly of said first automobile upon receipt of said driver operated control request signal emanating from said controller of said second automobile.
A method for towing a first automobile by the use of a second automobile wherein said first and said second automobiles each being of the type having a braking system, at least one driver operated assembly, and a controller which is coupled to said braking system and said at least one driver operated assembly, said method comprising:
- generating a brake request signal in said second automobile;
- generating a driver operated control signal in said second automobile;
- communicating said generated brake request signal to said controller which is resident within said second automobile;
- communicating said generated driver operated control signal to said controller which is resident within said second automobile;
- causing said controller within said second automobile to activate said braking system of said second automobile upon receipt of said brake request signal, thereby braking said second automobile by a certain first amount;
- causing said controller within said second automobile to activate said at least one driver operated assembly of said second automobile upon receipt of said driver operated control signal;
- causing said controller of said second automobile to generate a brake request signal to said controller of said first automobile;
- causing said controller of said second automobile to generate a driver operated control request signal to said controller of said first automobile;
- causing said controller of said first automobile to activate said braking system of said first automobile upon receipt of said brake request signal emanating from said controller of said second automobile, thereby braking said first automobile by a certain second amount which is less than said first amount, thereby causing said braking system of said second automobile to augment said braking system of said first automobile by supplementing the amount of braking provided by said braking system of said first automobile;
- and
- causing said controller of said first automobile to activate said at least one driver operated assembly of said first automobile upon receipt of said driver operated control request signal emanating from said controller of said second automobile.
