Problems solved by technology
Among them, the normal control and the entire signal chain have relatively complete implementation schemes, but there is no unified standard and specification for the strategies and methods of fault diagnosis.
[0003] In particular, due to the increasing complexity of software development and rapid iteration requirements for automotive controllers, as well as the increasingly perfect software architecture design based on AutoSAR, the idea of dividing modules with high cohesion and low coupling is currently aimed at the specific function of remote start. There is a phenomenon that the implementation and fault diagnosis are designed separately, and the interactive signal between the diagnosed fault and the normal logic control, and the interactive logic are unclear and easy to be delayed or oversensitive

Embodiment 1
[0041] In the existing technology, as the software development of the internal controller of the car becomes more and more complex, there is a phenomenon that the realization and fault diagnosis of the specific function of remote start are designed separately, and the interaction between the diagnosed fault and the normal logic control Signals and interaction logic are unclear and prone to delay or oversensitivity.
[0042] Wherein the remote start of the vehicle means that the vehicle engine can be controlled to start or stop by sending a remote command without carrying a key into the car, and the portable device usually has a display screen with user input (for example, touch, keyboard) and a user interface. Computing devices based on computing processors, portable devices include but are not limited to handheld devices, mobile devices, smart phones, laptop computers, tablet computers and e-readers, as a preferred method, usually the customer sends instructions through the cl...

The invention discloses a fault diagnosis method, device and vehicle for remote starting of a vehicle. The method includes the following steps: receiving a remote starting instruction from a remote starting device at a user end; obtaining the remote starting state of the vehicle; when the remote starting state is a starting process In the middle, judge whether there is the first fault information within the first preset time and whether the remote start of the vehicle is successful within the second preset time. If there is the first fault information or the remote start of the vehicle is unsuccessful, it is determined that the vehicle is not started ; When the remote start status is successful start, determine whether there is a second fault message within the third preset time and whether the vehicle remote start system has completed the remote start function reset within the third preset time, if there is a second fault message or If the remote start function is not reset, it is determined that the vehicle is not started. The present invention divides the start state and the fault type to ensure accurate identification of fault conditions at a specific time and eliminate the delay in fault judgment.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a fault diagnosis method, device and vehicle for remote starting of vehicles. Background technique [0002] At present, in the field of automotive electronics development, remote keyless start devices have become more and more popular. As one of the basic functions of smart cars, the remote start function of vehicles has been applied to some models with smart configurations. The remote start function is realized by the cooperation of modules such as the mobile phone APP on the client side, the Internet of Vehicles system, the keyless start system PEPS, and the engine electronic control unit. This function allows the car owner to send commands through the mobile phone to control the engine of the car to start when the car is far away from the car, providing power for the cooling and heating of the air-conditioning system in the car, so as to adjust the temperature inside the car ...
