Embodiment Construction

[0062] Such as figure 1 As shown, in an embodiment of the present invention, a method for controlling safe driving of a hybrid vehicle includes the following steps:

[0063]S1. Configure the trigger logic relationship of the control command in the automobile ECU; and configure the security level of the control command.

[0064] When the ECU controls the state of the car, some control commands have relatively low safety impact, such as controlling the execution of the on-board multimedia system, or obtaining the speed information of the vehicle, etc.; while some control commands may be closely related to the normal driving of the car, the safety level is relatively low. high. How to configure the specific security level can be flexibly configured.

[0065] Optionally, in the hybrid vehicle safety driving control method described in the present invention,

[0066] The trigger logic relationship in the step S1 includes:

[0067] Judging whether the corresponding execution tim...

Abstract

The invention discloses a hybrid vehicle safe driving control method. The hybrid vehicle safe driving control method comprises the following steps that S1, a trigger logic relation of a control instruction is configured in a vehicle ECU, and the control instruction security level is configured; S2, a state rollback trigger condition is configured for the control instruction with security level exceeding the preset levelin the ECU; S3, a rollback state value is configured for the control instruction with the security level exceeding the preset level in the ECU; S4, the ECU determines whether the trigger instruction matches the trigger logic relation when receives the trigger control instruction to execute the corresponding trigger instruction, and S5 is conducted when the trigger instruction matches the trigger logic relation and S6 is conducted when the trigger instruction does not match the trigger logic relation; S5, the ECU validates the trigger instruction legally, when validationpasses, a control instruction triggered by a trigger instruction is executed, and then the method is completed; S6, the ECU determines whether the security level of the corresponding control instruction is higher than the preset level, if yes, S7 is conducted; and S7, ECU obtains the vehicle state value associated with the control instruction corresponding to the trigger instruction.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a method for controlling safe driving of a hybrid vehicle. Background technique [0002] Existing new energy vehicles are different from traditional vehicles. More and more functions are handled by the central control system ECU of the vehicle, and some vehicles have realized the function of remote control. But on the other hand, the safety of the car is reduced. Once a criminal remotely controls the vehicle, the life safety of the user will be seriously threatened. Contents of the invention [0003] In view of this, the present invention provides a method for controlling safe driving of a hybrid vehicle. [0004] A method for controlling safe driving of a hybrid vehicle, comprising the steps of: [0005] S1. Configure the trigger logic relationship of the control command in the automobile ECU; and configure the safety level of the control command; [0006] S2. C...
