Abstract

Te invention provides a driving method of a drive-by-wire driving system and the drive-by-wire driving system, and relates to the technical field of automatic driving. A corresponding controller is arranged between an accelerator pedal position sensor and an engine management system in advance, and the controller can be used for checking the accelerator pedal position sensor and / or an upper-layercontrol instruction of an automatic driving upper-layer controller, so that when the accelerator pedal position sensor and / or the upper-layer control instruction are / is abnormal, an automatic drivingmode is switched to an artificial driving mode in time, the safety of automatic driving is guaranteed, and further the technical problem that in the prior art, safety of automatic driving is low due to the fact that fault detection cannot be carried out on the upper-layer control instruction of the automatic driving upper-layer controller and / or the accelerator pedal position sensor of a vehicle is solved.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a driving method of a drive-by-wire drive system and a drive-by-wire system. Background technique [0002] During the development process of automatic driving, the requirements for the driving system include: the driving system can be developed and highly intervened; there is safety protection in case of unreasonable upper-level instructions or component failures; the ability to complete the mode switching between automatic driving and manual driving. [0003] The existing solutions mainly include: through the electronic throttle system adaptive cruise control (Adaptive Cruise Control referred to as ACC) interface or the traction control system (Acceleration Slip Regulation referred to as ASR) interface to indirectly control the throttle to realize the driving control in automatic driving; by adding The actuator (that is, the electric motor) controls the opening of the ...
