Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings, to enable those skilled in the art referring to specification text
Word can be implemented accordingly.
As shown in Figure 1, the parking electric automobile control method of the present invention based on two-way CAN bus, is electronic
It is provided with the first CAN bus (i.e. CAN1 in Fig. 1) and the second CAN bus (i.e. CAN2 in Fig. 1) in automobile, further includes vehicle
Controller, gear controller, parking controller and electric machine controller.And the entire car controller, gear controller, parking control
Device and electric machine controller processed are respectively arranged between the first CAN bus and the second CAN bus, the entire car controller, gear control
The both ends of device processed, parking controller and electric machine controller connect with the first CAN bus and the second CAN bus respectively.
As shown in Figure 2 and Figure 3, the gear controller is respectively via the first CAN bus and the second CAN bus to described whole
Vehicle controller issues gear information, and the electric machine controller is respectively via the first CAN bus and the second CAN bus to the vehicle
Controller issues motor speed information, and the entire car controller combines the gear information and motor speed information that receive
Verification, to determine whether to meet parking condition；If the entire car controller is respectively via the first CAN bus by joint survey
With the second CAN bus to the parking controller send parking information, the parking controller to the parking information received into
Row joint verification, if by joint verification, the parking controller control parking brake movement.
In parking electric automobile control method of the present invention based on two-way CAN bus, by taking two lines road
Signal is transmitted to avoid the problem that transmission line is single in the prior art, i.e., improves signal biography by way of signal transmitting redundancy
Defeated reliability.Using the parking electric automobile control method of the present invention based on two-way CAN bus, can effectively avoid because
Dropout cause vehicle can not car slipping accident caused by parking occur, the personal safety of effective guarantee driver and passenger and vehicle
Safety avoids unnecessary economic loss, improves user experience.
Specifically, as shown in figure 4, the entire car controller is to the gear information via the first CAN bus received
It is verified, if the gear information meets parking condition, labeled as qualified gear information, to the joint school of gear information
It tests and passes through；Otherwise, the entire car controller further verifies the gear information via the second CAN bus received,
If the gear information meets parking condition, labeled as qualified gear information, the joint verification of gear information is passed through；If
Qualified gear information is not received yet, then combines verification and do not pass through, parking brake is failure to actuate.The entire car controller docking
What is received is verified via the motor speed information of the first CAN bus, if the motor speed information meets parking condition,
Labeled as qualified motor speed information, the joint verification of motor speed information is passed through；Otherwise, the entire car controller is into one
Step is verified to what is received via the motor speed information of the second CAN bus, if the motor speed information meets parking
Condition passes through the joint verification of motor speed information then labeled as qualified motor speed information；If not receiving qualification yet
Motor speed information, then combine verification do not pass through, parking brake is failure to actuate.If entire car controller is labeled as having been received
Qualified gear information and motor speed information, then combine verification and pass through.
Entire car controller described here verifies the joint of gear information and motor speed information, is to determine it
It is received to the gear information and motor speed information that are enough to enable the entire car controller to issue parking information.Conjunction described here
The gear information and motor speed information of lattice, which refer to, has been received the gear information for meeting pre-provisioning request and motor speed information,
As for gear information and motor speed information be specifically the first CAN bus transmission, or via the second CAN bus transmit and
Come, it is not important for entire car controller, it is important that the entire car controller has been received that qualified gear information
With motor speed information, entire car controller can issue parking information on this basis, in order to subsequent control parking brake
Just enough.
As shown in figure 5, in the parking electric automobile control method of the present invention based on two-way CAN bus, it is described to stay
Vehicle controller is verified to what is received via the parking information of the first CAN bus, if the parking information meets parking item
Part then passes through the joint verification of parking information；Otherwise, the entire car controller is further to receiving via the 2nd CAN
The parking information of bus is verified, if the parking information meets parking condition, is passed through to the joint verification of parking information；
If not receiving qualified parking information yet, combines verification and do not pass through, parking brake is failure to actuate.
The joint checking procedure that parking controller described here is carried out, its object is to ensure the parking controller
The parking information for meeting parking condition can be received, regardless of these parking information are transmitted via the first CAN bus,
Or it is transmitted via the second CAN bus.For parking controller, as long as receiving the parking letter for meeting parking condition
Breath, it will be able to control parking brake movement and realize parking.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited
In specific details and legend shown and described herein.
