In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.
Before the technical scheme is elaborated, the application scene of the technical scheme is briefly introduced so as to more clearly understand the technical scheme. With keyless entry and initiation systems (Passive Entry Passive Start, PEPS) in vehicle applications, more and more vehicles employ electronic steering column lock structures. In the prior art, when the PEPS system is used for controlling the steering column lock in the vehicle, the PEPS system needs to control the steering column lock actuator to execute the steering column locking operation after determining that the vehicle meets the locking condition of the electronic steering column. However, due to the problem of signal transmission delay between the steering column lock actuator and the electronic steering column lock control unit, in the actual use process, when the user restarts the vehicle in a short time after closing the vehicle, the steering column lock actuator is in a process of executing locking of the electronic steering column lock, but at this time, the state corresponding to the electronic steering column lock in the electronic steering column lock unit is in an unlocked state, and the vehicle will be started directly. Further, after the vehicle is started, the steering column lock actuator still executes the locking operation of the electronic steering column lock until the electronic steering column lock is successfully locked, so that the vehicle is in a locking state after the vehicle is started, and further potential safety hazards exist in the vehicle.
Example 1
Fig. 1 is a flowchart of a steering column lock control method according to an embodiment of the present invention, where the method may be applied to determining an actual locking state of a lock tongue execution module in a steering column lock when a vehicle is started, and performing an unlocking process on the steering column lock when the actual locking state is a locked state, and further according to a situation that a target vehicle is started by a vehicle start instruction, the method may be performed by a steering column lock control device, which may be implemented in a hardware and/or software form, and the steering column lock control device may be configured in a computing device that may perform the steering column lock control method.
As shown in fig. 1, the method includes:
s110, when an unlocking instruction corresponding to a steering column lock installed in a target vehicle is received, determining an actual locking state of a lock tongue executing module in the steering column lock.
The target vehicle may be understood as a vehicle with a PEPS system, for example, a car, a passenger car, or a truck, and in this technical solution, the type of the vehicle of the target vehicle is not specifically limited. The steering column lock is one kind of steering column locking device and consists of mainly lock rod, cam shaft, locking block, unlocking lever, unlocking button, etc. The function is simple, when the user pulls out the key from the key cylinder, the steering column is locked by the lock rod, so that even if other users start the engine without using the key (ignition switch), the automobile can not turn and can not be driven, thereby ensuring the safety of the vehicle. The unlock command is understood to be a command that controls the steering column lock to unlock the lock rod of the steering column. Under normal conditions, after the electronic steering column lock control unit sends an unlocking instruction to the steering column lock actuator, the steering column lock actuator unlocks a lock rod in the steering column according to the unlocking instruction, so that the vehicle can normally steer after the steering column is unlocked. In the technical scheme, the lock tongue executing module is a steering column lock executing mechanism in the electronic steering column lock. The actual lockout state includes a lockout state or an unblocked state.
In practical applications, after a target vehicle is started, a steering column lock installed in the target vehicle needs to be unlocked, so that a lock rod in the steering column lock in the target vehicle is in an unlocked state, and the target vehicle can normally steer. Therefore, after the target vehicle is started, the actual locking state of the lock tongue executing module in the steering column lock is detected first, and the actual locking state of the lock tongue executing module is determined. It is understood that when the actual lock state is the locked state, it means that the lock lever in the steering column lock in the target vehicle is locked, that is, the target vehicle cannot perform the steering operation. On the contrary, if the actual locked state is the unlocked state, it indicates that the lock lever in the steering column lock in the target vehicle is not locked, that is, the target vehicle can normally perform the steering operation.
Optionally, determining an actual locking state of the lock tongue execution module in the steering column lock includes: acquiring vehicle state information corresponding to a target vehicle; if the vehicle state information meets the preset locking detection condition, controlling a steering column lock in the target vehicle to carry out locking treatment; based on the lockout sensing module, an actual lockout condition corresponding to a deadbolt executing module in the steering column lock is determined.
Wherein the vehicle state information includes at least one of door state information, vehicle ignition information, and vehicle speed information. A lock sensor is understood to be a sensor for detecting the actual locking state of the bolt actuator module.
Specifically, when the vehicle state information of the target vehicle meets a preset locking detection condition, a locking instruction is sent to a lock tongue execution module of the target vehicle so as to control a steering column lock in the target vehicle to carry out locking processing. Specifically, if the vehicle state information of the target vehicle is that the vehicle door is opened and then closed, the vehicle ignition information is that the vehicle is closed, and the vehicle speed information is zero, it is determined that the target vehicle has satisfied a preset lock detection condition, and at this time, the steering column lock in the target vehicle is controlled to perform the lock processing.
Further, in order to determine whether the steering rotational speed is locked, a locking sensor in the target vehicle may detect a locking state of the lock tongue executing module, so as to obtain an actual locking state corresponding to the lock tongue executing module. Specifically, based on the lock sensing module, determining an actual lock state corresponding to a lock tongue executing module in the steering column lock includes: and detecting a lock tongue executing module in the steering column lock based on the locking sensing module to obtain a signal to be identified, and determining an actual locking state corresponding to the lock tongue executing module according to the signal to be identified.
The signal to be recognized may be understood as a signal for characterizing an actual locking state of the locking bolt execution module, for example, the signal to be recognized includes at least one of a voltage signal, a switching value signal, and an analog value signal.
For example, if the signal to be identified is a voltage signal, a voltage threshold may be preset, and when the signal to be identified is greater than the voltage threshold, it is determined that the actual locked state is the locked state, otherwise, it is determined that the actual locked state is the unlocked state.
The switching value signal is an acquisition and output of a discontinuous signal, and includes two states, namely 1 and 0, which can be used for representing the switching state of a circuit of the latch execution module, so as to determine the actual latching state of the latch execution module according to the switching state of the circuit. If the signal to be identified is a switching value signal, when the switching value signal is 1, the actual locking state can be determined to be an unlocked state, and when the switching value signal is 0, the actual locking state can be determined to be a locked state.
The analog signal includes a voltage analog signal and a current analog signal, and when the signal to be identified is greater than a preset current analog signal, the actual blocked state may be determined to be a blocked state, and when the signal to be identified is less than the preset current analog signal, the actual blocked state may be determined to be an unblocked state.
Optionally, determining, according to the signal to be identified, an actual locking state corresponding to the lock tongue execution module includes: determining an actual locking state corresponding to the lock tongue executing module as a locked state under the condition that whether a signal to be identified is larger than an identification signal threshold value or not; and determining the actual locking state corresponding to the lock tongue executing module as an unlocked state under the condition that whether the signal to be identified is smaller than or equal to the identification signal threshold value.
S120, determining a vehicle control mode corresponding to the target vehicle based on the actual locking state so as to start the target vehicle based on the vehicle control mode.
According to the technical scheme, when the unlocking instruction corresponding to the steering column lock installed in the target vehicle is received, the actual locking state of the lock tongue execution module in the steering column lock is determined, and in the technical scheme, before the steering column lock of the target vehicle is unlocked, the actual locking state of the lock tongue execution module in the steering column lock is determined to be the locked state, and then the steering column lock is unlocked based on the unlocking instruction. The aim of the arrangement is to avoid misjudgment of the actual locking state of the lock tongue execution module of the steering column lock when the target vehicle is suddenly started in a short time in the locking process, so that the situation that the steering column lock is mistakenly locked is caused. Further, a vehicle control mode corresponding to the target vehicle is determined based on the actual lock state to start the target vehicle based on the vehicle control mode. Specifically, when the actual locked state is the locked state, a vehicle start instruction may be sent to a vehicle controller of the target vehicle to start the target vehicle based on the vehicle start instruction; if the actual locking state is an unlocked state, the locking time of the lock tongue execution module of the steering column lock is required to exceed the preset locking time, or when the rotation times of the transmission gear in the steering column lock reach the preset rotation times, the actual locking state is switched to the locked state, and then the target vehicle is started based on the vehicle starting instruction in the locked state. The problem that the actual locking state of the lock tongue executing module of the steering column in the vehicle is inconsistent with the locking state obtained by the steering column lock control unit, so that the vehicle is wrongly locked, and potential safety hazards exist in the vehicle is solved, the unlocking processing is carried out on the steering column lock on the premise that the actual locking state of the lock tongue executing module in the steering column lock is determined to be the locked state, and the vehicle is started according to the vehicle starting instruction, so that the effect of wrongly locking the steering column lock is prevented.
Example two
Fig. 2 is a flowchart of a steering column lock control method according to a second embodiment of the present invention, optionally, when an actual locked state is a locked state, unlocking the steering column lock based on an unlocking instruction, and after the unlocking is successful, sending a vehicle start instruction to a vehicle controller of a target vehicle to start the target vehicle based on the vehicle start instruction.
As shown in fig. 2, the method includes:
s210, when an unlocking instruction corresponding to a steering column lock installed in a target vehicle is received, determining an actual locking state of a lock tongue executing module in the steering column lock.
S220, when the actual locking state is the locked state, unlocking the steering column lock based on the unlocking instruction.
Specifically, when the actual locking state is the locked state, it indicates that the lock tongue executing module in the steering column has locked the lock rod, that is, the target vehicle cannot perform steering operation. Further, after the locking operation is completed, the steering column lock control unit may send an unlocking instruction to the lock tongue execution module of the steering column lock, so that the lock tongue execution module performs unlocking processing on the steering column lock according to the unlocking instruction.
And S230, after the unlocking is successful, a vehicle starting instruction is sent to a vehicle controller of the target vehicle so as to start the target vehicle based on the vehicle starting instruction.
The vehicle start command is understood to be a command for controlling the start of the vehicle.
Specifically, after the steering column lock in the target vehicle is successfully unlocked, the vehicle controller can start the target vehicle according to the received vehicle start command. The target vehicle can be steered normally at this time.
Optionally, determining a vehicle control mode corresponding to the target vehicle to start the target vehicle based on the vehicle control mode includes: under the condition that the actual locking state is an unlocked state, determining whether the locking time corresponding to the lock tongue execution module is longer than a preset locking time; if yes, a locking signal is fed back to the steering column lock control module, so that the steering column lock control module switches the actual locking state to the locked state, unlocking processing is carried out on the steering column lock based on an unlocking instruction, and after the unlocking is successful, a vehicle starting instruction is sent to a vehicle controller of the target vehicle so as to start the target vehicle; if not, after the locking duration reaches the preset locking duration, unlocking the steering column lock based on the unlocking instruction, and after the unlocking is successful, sending a vehicle starting instruction to a vehicle controller of the target vehicle so as to start the target vehicle.
The locking time is the time from the sending of the locking instruction to the current moment, and the lock tongue executing module executes locking on the steering column lock. The preset locking duration is the maximum duration of locking the steering column lock by the preset lock tongue executing module.
Specifically, when determining whether the locking operation of the steering column lock is completed by the lock tongue executing module, the determination may be made by a locking time period corresponding to the lock tongue executing module. If the locking time length is longer than the preset locking time length, the fact that the locking time length of the lock tongue execution module exceeds the preset maximum locking time length is indicated, for example, 5s, at the moment, it can be determined that the steering column lock has completed locking operation, the actual locking state needs to be switched to the locked state, after an unlocking instruction is received, unlocking processing is conducted on the steering column lock according to the unlocking instruction, and then the target vehicle is started according to the vehicle starting instruction.
Otherwise, if the locking duration is smaller than the preset locking duration, determining that the actual locking state is the locked state when the locking duration reaches the preset locking duration, unlocking the steering column lock according to the received unlocking instruction, and starting the target vehicle after the vehicle starting instruction is received.
Optionally, determining whether the number of rotations of the transmission gear in the steering column lock reaches a preset number of rotations; if yes, switching the actual locking state to the locked state based on the steering column lock control module; if not, the transmission gear is controlled to continue rotating until the rotation times reach the preset rotation times.
In practical applications, in order to determine whether the actual locking state corresponding to the steering column lock is a locked state, the judgment may be further performed according to the number of rotations of the transmission gear in the steering column lock. Specifically, if the rotation number of the transmission gear reaches the preset rotation number, determining that the actual locking state is the locked state, otherwise, if the rotation number is smaller than the preset rotation number, controlling the transmission gear to continue rotating until the rotation number reaches the preset rotation number, and switching the actual locking state to the locked state.
According to the technical scheme, when the unlocking instruction corresponding to the steering column lock installed in the target vehicle is received, the actual locking state of the lock tongue execution module in the steering column lock is determined, and in the technical scheme, before the steering column lock of the target vehicle is unlocked, the actual locking state of the lock tongue execution module in the steering column lock is determined to be the locked state, and then the steering column lock is unlocked based on the unlocking instruction. The aim of the arrangement is to avoid misjudgment of the actual locking state of the lock tongue execution module of the steering column lock when the target vehicle is suddenly started in a short time in the locking process, so that the situation that the steering column lock is mistakenly locked is caused. Further, a vehicle control mode corresponding to the target vehicle is determined based on the actual lock state to start the target vehicle based on the vehicle control mode. Specifically, when the actual locked state is the locked state, a vehicle start instruction may be sent to a vehicle controller of the target vehicle to start the target vehicle based on the vehicle start instruction; if the actual locking state is an unlocked state, the locking time of the lock tongue execution module of the steering column lock is required to exceed the preset locking time, or when the rotation times of the transmission gear in the steering column lock reach the preset rotation times, the actual locking state is switched to the locked state, and then the target vehicle is started based on the vehicle starting instruction in the locked state. The problem that the actual locking state of the lock tongue executing module of the steering column in the vehicle is inconsistent with the locking state obtained by the steering column lock control unit, so that the vehicle is wrongly locked, and potential safety hazards exist in the vehicle is solved, the unlocking processing is carried out on the steering column lock on the premise that the actual locking state of the lock tongue executing module in the steering column lock is determined to be the locked state, and the vehicle is started according to the vehicle starting instruction, so that the effect of wrongly locking the steering column lock is prevented.
