Problems solved by technology

However, muck truck operating companies or drivers often dismantle the smart vehicle terminal privately or even maliciously for economic benefits, or make the locking circuit invalid by short-circuiting, thereby avoiding remote locking control, and the locking effect is poor, resulting in the remote management platform being unable to Effective control and supervision of muck trucks

Embodiment 1

[0085]Vehicle-mounted terminal 2 is initialized. According to the restriction requirements of the city A where the muck truck operates, the initial value of the restriction type is pre-stored in the EEPROM of ECU 1. The vehicle-mounted terminal ID of the vehicle-mounted terminal 2 installed on the muck truck and the fixed key used for verification. The vehicle-mounted terminal 2 sends a vehicle lock function activation message (0CFF41FD) to the ECU 1, and the vehicle lock function activation message includes 0x01, TCD_ID and a fixed key. Among them, 0x01 means that the limit type value of the locked car is A, which can be used to limit any one or more functions of the engine speed, vehicle speed, and engine start; TCD_ID represents the vehicle terminal ID.

[0086] ECU 1 judges: the limit type value A is inconsistent with the limit type initial value 0, TCD_ID is consistent with the vehicle terminal ID, and the fixed key matches, and the activation condition is met, the limit ...

Embodiment 2

[0089] Vehicle-mounted terminal 2 is initialized. According to the restriction requirements of the city B where the muck truck operates, the initial value of the restriction type is pre-stored in the EEPROM of ECU 1. The vehicle-mounted terminal ID of the vehicle-mounted terminal 2 installed on the muck truck and the fixed key used for verification. The vehicle-mounted terminal 2 sends a message for activating the vehicle locking function (0CFF41FD) to the ECU 1, and the message for activating the vehicle locking function includes 0x02, TCD_ID and a fixed key. Among them, 0x02 means that the limit type value of the locked car is B, which can be used to limit the engine speed function; TCD_ID means the vehicle terminal ID.

[0090] ECU 1 judges: the limit type value B is inconsistent with the limit type initial value 0, the TCD_ID is consistent with the vehicle terminal ID, and the fixed key matches, and the activation condition is met, the limit type value B is stored in EEPRO...

Embodiment 3

[0093] Due to engineering needs, a city government newly purchased two muck trucks. Because of an operation error on the muck truck remote management platform 3, the on-board terminal 2 of the muck truck I was equipped with a fixed key for the muck truck II, and the muck truck II The vehicle-mounted terminal 2 configured with the fixed key of the muck truck 1. After the muck truck is powered on, ECU 1 judges that the fixed key in the received vehicle lock function activation message (0CFF41FD) does not match the fixed key pre-stored in the EEPROM, and if the activation conditions are not met, the activation of the vehicle lock function fails. . ECU1 sends a response message (18FF2300) to the vehicle terminal 2, and the response message (18FF2300) includes 0 (the first digit, indicating that the activation of the lock function failed) and 0x0011 (the second and third digits, indicating the cause of the activation failure of the lock function) , that is, the fixed key does not ...

Abstract

The invention discloses a car lock control method for a diesel engine dregs truck. The car lock control method is realized based on a car lock control device. The car lock control device includes an ECU (1), a vehicle-mounted terminal (2), and a remote management platform for a muck truck (3) Wirelessly connect with the vehicle-mounted terminal; the method includes steps: 1. The vehicle-mounted terminal initializes and activates the car lock function; 2. The muck truck is powered on, and the vehicle-mounted terminal sends a lock-up control message to the ECU according to the restriction type, and the ECU controls the vehicle lock function. The earth truck executes the locking action; the type A vehicle locking message includes the restricted function type and its function restriction parameters, random code and check code, and the B type vehicle lock message includes the restricted function type and its function restriction parameters; 3. ECU passes The broadcast message feeds back the lock status to the vehicle terminal. The invention realizes the engine speed, vehicle speed and start-up limitation of the muck truck through the message communication between the vehicle-mounted terminal and the ECU, and realizes the real-time remote control and management of each muck truck by the muck truck remote management platform.

Description

technical field [0001] The invention relates to a control method for managing muck trucks, in particular to a lock control method for diesel engine muck trucks. Background technique [0002] The muck truck is a large vehicle used to transport construction materials such as sand and gravel. Due to the large size of the vehicle and the high cab, the driver of the muck truck has many blind spots during driving, and it is a vehicle with frequent traffic accidents. At the same time, due to the large deadweight and load of the muck truck, once a traffic accident occurs, it is very easy to cause rollover and spillage of building materials, which in turn causes greater personal injury and property loss. In order to ensure smooth and safe traffic, various cities have put forward restrictions on the operation of muck trucks in accordance with relevant laws and regulations, such as limiting vehicle speed, limiting engine speed, and limiting starting. [0003] In the remote locking con...
