Fault validation and handling method for vehicle gearbox

Abstract

The invention discloses a fault validation and handling method for a vehicle gearbox. A transmission controller receives electrical component fault signals and software computing fault signals on thedouble-clutch gearbox, and faults related with the faults of the double-clutch automatic gearbox are set into three types through a fault processing and communication module; and the fault types, configuration fault properties and fault related information are determined, the fault signals and corresponding alternative strategies are determined according to the corresponding properties set by theconfiguration fault properties, the gearbox enters into a safety state through the transmission controller, after the fault processing and communication module determines that the faults of the double-clutch gearbox disappear, the conditions and the alternative strategies are withdrawn exit according to the alternative strategies of the configuration fault properties, and the gearbox system logs out a safety state to get right. The fault validation and handling method for the vehicle gearbox ensures safety of the automatic gearbox under multiple fault types, ensures safety of vehicle allowanceand reduces damage of faults of the double-clutch automatic gearbox.

Description

technical field [0001] The invention relates to the field of transmission fault processing and communication, in particular to a method for confirming and processing a transmission fault of a vehicle. Background technique [0002] As one of the important power components of a car, the transmission plays an important role in transmitting power and changing direction. When the gearbox fails, it has a major impact on the safety of the vehicle equipped. With the development of automobile technology, automatic transmissions, especially dual-clutch transmissions, use a large number of electrical devices, electronic devices, and programmable electronic devices. The use of these electrical-related devices greatly increases the possibility of failure, making automatic transmissions The probability of failure is greatly increased. At the same time, how to detect, confirm and deal with transmission faults, especially when multiple faults occur, how to deal with transmission faults ac...
