Embodiment 1

[0046] In order to solve the above problems, the electronic shifter can be safely and effectively used on heavy trucks, such as figure 1 and image 3 As shown, the present invention proposes a shifting system of a multiplexed multi-gear shifter, including a shift lever, a Hall angle sensor and a main control chip. The position of the shift lever when the vehicle is in neutral is Initial station, where:

[0047] The shift lever is used to switch between the first station to the eighth station and the initial station (N) when shifting gears;

[0048] The Hall angle sensor is used to send the corresponding first gear signal to the sixth gear according to the change of the magnetic flux at each position when the shift lever is switched from the first position to the sixth position (1 to 6) bit signal;

[0049] The main control chip is used to output a control signal according to the gear position signal to control the vehicle to shift gears;

[0050] The main control chip is a...

Embodiment 2

[0069] like figure 2 As shown, the present invention also proposes a shifting method of a multiplexed multi-gear shifter, including a shift lever, a Hall angle sensor and a main control chip, and the position of the shift lever when the vehicle is in neutral is Initial station, including steps:

[0070] S1: Receive the change of the magnetic flux of the Hall angle sensor when the shift lever is switched from the first position to the sixth position, and send the corresponding first gear signal to the sixth gear signal;

[0071] S2: switch the vehicle gear according to the gear signal output control signal;

[0072] S3: Determine whether the vehicle is in the sixth gear and the first gear signal is received, if so, switch the first gear signal to the sixth gear signal to the seventh gear signal to the twelfth gear signal, and control The vehicle is switched to the seventh gear, if not, then return to step S2;

[0073] S4: Switching the gear position of the vehicle according...

Abstract

The invention discloses a shifting system and method of a multiplexed multi-gear shifter, which relates to the field of automobile control and includes a shift lever, a Hall angle sensor and a main control chip, wherein the shift lever is used for shifting When shifting, switch between the first station to the eighth station and the initial station; the Hall angle sensor is used to switch from the first station to the sixth station of the shift lever, according to the magnetic flux at each station Change and send the corresponding first gear signal to the sixth gear signal; the main control chip controls the vehicle to shift gears according to the gear signal output control signal, and judges and corrects the gear signal when switching between high and low gears. The present invention avoids the misjudgment of the gear signal by redefining the gear position signal and correcting the gear position signal under special circumstances, understands the driver's shifting needs more accurately, and solves the problem of the electronic shifter being used in heavy duty situations. The shift logic judgment problem on the car.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to a shifting system and method of a multiplexed multi-gear shifter. Background technique [0002] The biggest difference between trucks and ordinary vehicles is that the weight and displacement of trucks are much larger, especially for heavy trucks. There is enough torque to drive the vehicle forward, so the common gears of Sinotruk are 8-12 gears. General heavy trucks are mostly diesel vehicles, and the working speed range of diesel engines is much smaller than that of gasoline engines, about 1000-2500 rpm. In order to exert the maximum torque and efficiency of the engine within the speed range of 0-120 km / h, more gears are required than gasoline engines. Generally, the more gears of Sinotruk, the higher the utilization of engine power. In addition, in different road conditions, more gears can be used to adapt to achieve the best ratio of vehicle speed and torque output. [0...
