In order to realize above purpose, car body controller provided by the invention comprises: obtain subelement, it is used to obtain wheel speed sensors signal and head light working state signal; Judgment sub-unit, whether it is used for according to having the wheel speed sensors signal to judge whether vehicle is in motoring condition, and judge according to the head light working state signal whether head light is lighted; The control subelement, it is used for judging when judgment sub-unit that vehicle is in to control when motoring condition and head light are not lighted and lights daytime running lamps.
Preferably, described car body controller further comprises: the fault detection subelement, and it is used for daytime running lamps being carried out fault detection before obtaining wheel speed sensors signal and head light working state signal obtaining subelement; If detect the daytime running lamps fault, then close above-mentioned work of obtaining subelement, judgment sub-unit and control subelement; If do not detect the daytime running lamps fault, then above-mentioned subelement, judgment sub-unit and the control subelement of obtaining begins to carry out work.
Preferably, described car body controller is controlled at and shows on the gauge panel that daytime running lamps is in faulty condition or is in normal working.
Preferably, described car body controller obtains the wheel speed sensors signal by high-speed CAN bus.
Correspondingly, the invention provides a kind of daytime running lamps control method, comprising: obtain wheel speed sensors signal and head light working state signal; Judge whether to get access to the wheel speed sensors signal, if then carry out following steps, otherwise close daytime running lamps; Judge according to the head light working state signal whether head light is lighted, if then light daytime running lamps, otherwise close daytime running lamps.
Preferably, described method further comprises: before obtaining wheel speed sensors signal and head light working state signal, daytime running lamps is carried out fault detection; If detect the daytime running lamps fault, then do not carry out above-mentioned steps; If do not detect the daytime running lamps fault, then begin to carry out above-mentioned steps.
Preferably, described method further comprises: show that on gauge panel daytime running lamps is in faulty condition or is in normal working.
In the daytime running lamps control setup and control method that the present invention proposes, the signal and the head light working state signal that only need obtain wheel speed sensors can judge whether to open daytime running lamps, its control method is simple, solved in the prior art the control method of daytime running lamps complicated problems too, had an advantages of high practicability.In addition, described car body controller obtains the signal of wheel speed sensors by high-speed CAN bus and daytime running lamps is controlled, and accuracy and real-time that its signal obtains are higher, and therefore the accuracy and the real-time of described control method are higher.
Description of drawings
Fig. 1 is an embodiment of the invention daytime running lamps control setup structural representation;
Fig. 2 is an embodiment of the invention daytime running lamps control method diagram of circuit.
The specific embodiment
For making those skilled in the art understand technical scheme of the present invention better, a kind of daytime running lamps control setup of the present invention and control method are described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, embodiment of the invention car body controller (Body Control Module, be called for short BCM) be connected with wheel speed sensors, head light and daytime running lamps respectively, being used for detection wheel speed sensors signal and head light working state signal, and lighting and closing according to testing result control daytime running lamps.
Specifically, wheel speed sensors is used to obtain the wheel speed signal of vehicle, when wheel speed sensors has signal, shows that promptly vehicle is in motoring condition, when wheel speed sensors does not have signal, shows that promptly vehicle remains static down, need not to open daytime running lamps this moment.Head light is the illumination that is used for the night travel road, that is to say, when vehicle is travelling under the dim light environment or during at night running, head light is lighted, and when vehicle travelled under the light bright light environments or travels by day, head light was closed.And lighting and closing of daytime running lamps is just in time opposite with head light.That is to say in the present invention, have only when vehicle is in motoring condition and head light and does not light, BCM control daytime running lamps is lighted, thereby improves travel safety.
In order to realize above technical conceive, as shown in Figure 1, BCM of the present invention comprises and obtains subelement, judgment sub-unit and control subelement, wherein, obtains subelement and is used to obtain wheel speed sensors signal and head light working state signal; Whether judgment sub-unit is used for according to having the wheel speed sensors signal to judge whether vehicle is in motoring condition, and judge according to the head light working state signal whether head light is lighted; The control subelement is used for judging when judgment sub-unit that vehicle is in to control when motoring condition and head light are not lighted and lights daytime running lamps.
In addition, BCM also can comprise the fault detection subelement, and it is used for daytime running lamps being carried out fault detection before obtaining wheel speed sensors signal and head light working state signal obtaining subelement.If detect the daytime running lamps fault, then close above-mentioned work of obtaining subelement, judgment sub-unit and control subelement, and can on gauge panel, show the daytime running lamps fault.If do not detect the daytime running lamps fault, then above-mentioned subelement, judgment sub-unit and the control subelement of obtaining begins to carry out work, and can show that on gauge panel daytime running lamps is normal.
Here point out that BCM obtains the signal of wheel speed sensors by high-speed CAN bus, in case vehicle enters under the motoring condition, BCM can obtain the signal of wheel speed sensors and daytime running lamps is controlled, and its signal obtains accuracy and real-time is higher.
Below, with reference to Fig. 2 the daytime running lamps control method that the BCM by the embodiment of the invention carries out is described.Following steps that described control method comprises:
Step S201, obtain wheel speed sensors signal and head light working state signal;
Step S202, judge whether to get access to the wheel speed sensors signal, if, show that then vehicle is in motoring condition, this moment execution in step S203, otherwise, show that vehicle remains static, need not to open daytime running lamps, this moment execution in step S205;
Step S203, judge according to the head light working state signal whether head light is lighted, if, show then that vehicle travels or at night running under the dim light environment, this moment execution in step S204, otherwise, show that vehicle travels or travels by day under the light bright light environments, at this moment execution in step S205;
Step S204, light daytime running lamps;
Step S205, close daytime running lamps.
In addition, as mentioned above, also can before execution in step S201, carry out fault detection to daytime running lamps.If detect the daytime running lamps fault, then do not carry out above-mentioned steps, and can on gauge panel, show the daytime running lamps fault.If do not detect the daytime running lamps fault, then begin execution in step S201, and can show that on gauge panel daytime running lamps is normal.
Be understandable that above embodiment only is the illustrative embodiments that adopts for principle of the present invention is described, yet the present invention is not limited thereto.For those skilled in the art, without departing from the spirit and substance in the present invention, can make various modification and improvement, these modification and improvement also are considered as protection scope of the present invention.
