Abstract
A control system for a drag race vehicle limits engine RPM to a selected Launch RPM limit when the vehicle is staged at the starting line and which limits engine RPM to an Elapsed Time RPM limit after the vehicle is shifted to high gear. The Launch RPM control is controlled by the same driver-controlled Launch switch which controls the line lock or transmission brake solenoid, so that the Launch RPM limit is removed at the same time that the vehicle is permitted to move forward. The Elapsed Time RPM control is actuated by a second driver-controlled Elapsed Time Enable switch. The control system is particularly useful for Super Class drag racers, in which the winner must be the first to the finish line without going under a predetermined elapsed time.
Claims8
For use in a drag racing vehicle which has means for preventing movement of the vehicle when the vehicle is at a starting line and a first driver-controlled switch for controlling operation of the means for preventing movement, the improvement comprising:
- Launch RPM control means for limiting engine RPM of the vehicle to a selected Launch RPM limit, the Launch RPM control means being operably connected to the first driver-controlled switch to be operable simultaneously with the means for preventing movement.
A control system for a drag racing vehicle comprising:
- a solenoid means for preventing movement of the vehicle when energized;
- engine RPM control means connected to an ignition system of the vehicle for limiting engine RPM to a selected value as a function of an impedance connected to the engine RPM control means;
- Launch RPM impedance means for providing a first impedance representative of a selected Launch RPM limit;
- a driver-controlled Launch switch having a first state and a second state, the Launch switch being connected to the solenoid means so that the solenoid means is energized when the Launch switch has a first state and is deenergized when the Launch switch has a second state;
- and
- means for connecting the Launch RPM impedance means to the engine RPM control means to cause the engine RPM to be limited to the selected Launch RPM limit when the Launch switch has the first state and for disconnecting the Launch RPM impedance means from the engine RPM control means when the Launch switch has the second state.
