Abstract
The invention relates to a method for externally awakening a CAN (Controller Area Network) bus in the parking status, which comprises the following steps of: sending a specific signal to an MCU (Micro Controller Unit) of a vehicle detection system by an external device; and awakening the CAN but to work, and outputting vehicle status data to a vehicle-mounted terminal. By adopting the technical scheme, the vehicle detection system can awaken the CAN bus at any time to detect the vehicle status, and timely and accurate information is provided for users.
Description
Technical field
The present invention relates to vehicle testing technique, particularly under dead ship condition, detect the system and method for vehicle condition.
Background technology
Automobile detection system in the prior art (OBD II) is when dead ship condition; The canbus bus does not all have signal on the port, at this moment, if the car owner need know the state of present automobile; To have no way of obtaining the related data of vehicle condition, bring a lot of inconvenience to the user.
Summary of the invention
The present invention provides a kind of method of under dead ship condition, waking the canbus bus up, adopts the outside mode of waking up, solves the technical matters that can not in time obtain vehicle condition information in the prior art.
The present invention solves the problems of the technologies described above and the method for taking under dead ship condition outside to wake the canbus bus up may further comprise the steps: A. sends signal specific by external unit to the MCU of automobile detection system; Said external unit sends the wake-up signal that signal specific comprises that automobile services system or automotive theft proof system send to MCU; Perhaps wake-up signal comprises information from customer mobile terminal to the automobile services system that sent the request detection vehicle condition by; After this information is received by the automobile services system; Send wake-up signal, the solicited message that the user sends comprises to the automobile services system to be sent note, dials the phone of automobile services system or the information that login automobile services system website transmits; B. wake the canbus bus up and carry out work, to car-mounted terminal output vehicle condition data.
This system of this waken system comprises automobile power source, ignition switch ACC line, the switch relay that is arranged on this ACC line that is connected with automobile power source, the external unit of controlling this switch relay, connect the automobile detection system MCU and the car-mounted terminal of canbus bus.This system can be divided into following concrete steps in the B step; B1. at the ACC of automobile ignition switch line switch relay is set; After B2.MCU receives signal specific, the moment connection of control ignition circuit, the work of canbus bus is to car-mounted terminal output vehicle condition data.
The present invention adopts above-mentioned technical scheme, makes this automobile detection system can wake the canbus bus at any time up, and vehicle condition is detected, and to the user information promptly and accurately is provided.
description of drawings Fig. 1 is the system schematic of the canbus of waking up bus according to the invention.
Embodiment
Of the present invention in conjunction with above-mentioned description of drawings with regard to specific embodiment.
By can knowing among Fig. 1, the system that the outside is waken the canbus bus up under this dead ship condition comprises automobile power source V, the ignition switch K that is connected with automobile power source, be arranged on the switch relay J of this ACC line, control this switch relay Automobile Detection unit U, connect the automobile detection system MCU and the car-mounted terminal of canbus bus.The method of specifically waking up may further comprise the steps: the MCU of A. automobile detection system sends signal specific, and the signal specific that MCU sent is that software control is periodically sent or outer signals control is sent; And the signal that outer signals signal that to be automotive theft proof system send or automobile services system send, the automobile services system sends to the automobile services system according to customer mobile terminal and comprises note, dials the phone of automobile services system or the information of login automobile services system website request detection vehicle condition is sent signal; B. wake the canbus bus up and carry out work, to car-mounted terminal output vehicle condition data.
The mode that the present invention adopts external signal to wake up starts the work of canbus bus, under dead ship condition, can also the detection starting system, and can obtain the relevant information of vehicle condition timely and accurately, for the user provides quality service more.Send signal specific and comprise following concrete mode; The wake-up signal that first automobile services system or automotive theft proof system send to MCU; This mode of waking up is that the automobile services system regularly sends signal to the MCU of automobile detection system; Regularly detect the state of automobile, when abnormal conditions, in time notify the user.It two is that the user is need understand the state of present own automobile the time; Send to the automobile services system by customer mobile terminal and to comprise to the automobile services system and send note, dial the phone of automobile services system or login the information that the automobile services system website transmits the request detection vehicle condition; After this information is received by the automobile services system; Send wake-up signal, above mode is suitable for the vehicle that can wake up through instruction.It three is, when automotive theft proof system is sensed vehicle action (for example switch car door etc.), sends signal and gives MCU.
And for the vehicle that can not wake up through instruction, waken system comprises automobile power source V, the ignition switch K that is connected with automobile power source, be arranged on the switch relay J of this ACC line, control this switch relay Automobile Detection unit U, connect the automobile detection system MCU and the car-mounted terminal of canbus bus.Step B comprises step by step following in the wakeup process: B1. is provided with switch relay at the ACC of automobile ignition switch line parallel; After B2.MCU received signal specific, switch relay was closed, the moment connection of control ignition circuit, and the work of canbus bus is to car-mounted terminal output vehicle condition data.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
