Abstract
The invention relates to a controlling method for preventing interlocking between gears of a six-speed automatic transmission, wherein an anti-interlocking valve is not arranged on a mechanical body, the interlocking between the gears of an automatic transmission is reduced by a software means in accordance with five failure combinations which can cause the interlocking between the gears through a logic control of an electronic control unit. With adoption of the software means, according to the controlling method disclosed by the invention, possibility of the interlocking between the gears of the automatic transmission is reduced to the greatest extent, so that the possibility of the interlocking between the gears of the automatic transmission is effectively reduced, thereby ensuring traffic safety and guaranteeing service life of the transmission.
Description
Technical field
The present invention relates to a kind of automatic transmission control technique, particularly a kind of 6 gear transmissions prevent the controlling method of gear interlocking.
Background technique
At present, universal day by day along with automatic transmission makes the constantly innovation of automatic transmission technology.The raising that the Consumer requires for vehicle safety, automatic transmission is as the important driving mechanism of vehicle, and its Security also came into one's own originally more.Interlocking phenomenon between gear can take place in the solenoid valve combination of mistake, and 2 of speed changers or 2 above gears are worked simultaneously, causes input and output shaft locked, and the speed changer body is caused damage, influences the speed changer life-span.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the above-mentioned technology; A kind of software control method of automatic transmission functional safety is provided; Pass through software approach; At utmost reduce the possibility of interlocking between A/T gear position, 6 gear transmissions that effectively guarantee vehicle driving safety prevent the controlling method of gear interlocking.In order to achieve the above object; The technological scheme that the present invention adopts is: anti-interlock valve is not set on basic machine; But the logic control through electronic control unit to 5 kinds of failure combination that possibly cause interlocking between gear, reduces interlocking between A/T gear position through software approach.Advantage of the present invention is: through software approach, at utmost reduce the possibility of interlocking between A/T gear position, effectively reduce the possibility of interlocking between A/T gear position, guarantee traffic safety, guarantee the speed changer life-span.
Description of drawingsFig. 1 is the interlocking monitoring process chart of patent of the present invention.
EmbodimentBelow in conjunction with accompanying drawing embodiments of the invention are described in further detail.Can know that by Fig. 1 the present invention is not provided with anti-interlock valve on basic machine, but the logic control through electronic control unit to 5 kinds of failure combination that possibly cause interlocking between gear, reduces interlocking between A/T gear position through software approach.Described 5 kinds of failure combination are: solenoid valve inefficacy, input shaft inefficacy, output shaft inefficacy, ABS failure and oil temperature lost efficacy.Described solenoid valve lost efficacy for solenoid valve opens circuit, short circuit.Described input shaft lost efficacy for the maximum changing down K1 that input shaft allows is set, and through the transfer input shaft speed sensors input shaft rotating speed was monitored, if the input shaft rotating speed occurring significantly reduces suddenly, actual changing down is greater than K1, then by interlock process.Described output shaft lost efficacy for the maximum changing down K2 that output shaft allows is set, and through OSS the output shaft rotating speed was monitored, if the output shaft rotating speed occurring significantly reduces suddenly, actual changing down is greater than K2, then by interlock process.Described ABS failure is that the maximum changing down K3 that the speed of a motor vehicle allows is set, and ins conjunction with ABS the speed of a motor vehicle is monitored, if no brake signal and the speed of a motor vehicle occurs and significantly reduce suddenly, actual changing down is then pressed interlock process greater than K3.Described oil temperature lost efficacy for the maximum oil temperature T1 of permission is set, and gearbox oil temperature is monitored, and oil is warm during greater than T1; Vehicle is lighted the high temperature alarm lamp; And start the speed changer high temperature protection, prevent that the too high solenoid valve that causes of oil temperature, wire harness lost efficacy (open circuit, short circuit etc.), thereby cause interlocking.Solenoid valve lost efficacy, input shaft lost efficacy, output shaft lost efficacy, the failure conditions of ABS failure if take place, and then speed changer gets into sloping row mode operation.
