Embodiment Construction

[0008] The addition of the reversing safety signal 210 and the safety deceleration signal improves the safe driving of the automobile to a higher level. The safety signal may be an output signal of an auxiliary reversing system such as radar, ultrasonic wave, or video. When there are people, animals or obstacles behind, what the gearbox control system can do is to exit the reverse gear as soon as possible, and immediately stop providing the power to the body to reverse, so that the braking system can stop the car as soon as possible.

[0009] Similar to the reversing situation, in the forward situation, when the approved external controllers, such as the engine control system, chassis control system, driving control system, etc., find that it is necessary to quickly decelerate, they can notify the automatic transmission control system to automatically decide to switch in according to the specific situation. The low gear uses the engine as a load to reduce the speed of the vehi...

Abstract

The invention disclose a novel mechanical automatic gearbox control system. The system employs safety signal in vehicle for auxiliary control, when human, animal, or barriers exist at behind, the gearbox control system immediately stops to supply power for withdrawing so as to stop the vehicle with a brake system. In condition of advancing, when approval other controllers in the vehicle find it is needed to quickly decelerate, the automatic gearbox control system is informed to determine change into low shift engine as load to decelerate according to particular condition, the clutch is separated to avoid effect of the inertia of the engine to the vehicle to quickly decelerate. The stable slowly-advancing quickly-withdrawing self-learning shift strategy complete full-automation with two parts of: stable slowly-advancing self-learning shift strategy and stable quickly-withdrawing self-learning shift strategy. The invention defines a function of clutch separation distance d and time t, and a function of output shaft slip difference h and time t, and stable slowly-advancing quickly-withdrawing self-learning method and parameter selection.

Description

technical field [0001] The invention relates to mechanical automatic transmission control, in particular to a mechanical automatic transmission control system with stable self-learning shifting. Background technique [0002] Mechanical automatic transmissions can be divided into two categories: hydraulic type and electric type according to the different operating mechanisms. Their existence is to reduce the labor intensity of the driver and improve efficiency. The hydraulic mechanical automatic transmission uses a hydraulic device to switch the meshing of the gear set, while the electric mechanical automatic transmission uses an electric device such as a motor or an electromagnet to switch the meshing of the gear set. Since the structure of the mechanical automatic transmission is much simpler than that of the traditional automatic transmission, and the cost is low, more and more applications are obtained. However, no matter what kind of mechanical automatic transmission, t...
