Problems solved by technology
There is also program start on the previous special vehicles, but the function is relatively simple, and the control accuracy is low. There is no accurate calculation of the starting current and generator D+ signal, and it can no longer meet the requirements of the new generation of special vehicles for program start.

Embodiment Construction
[0025] Schematic diagram of the composition of the program starting system in this embodiment, such as figure 1 shown. The program starting system includes an electrical integrated control box, a start button 1 , an electrical integrated control box 2 , a starting relay 3 , a starter 4 , a starting current sensor 5 and a generator 6 . The program starting control algorithm runs in the electrical integrated control box, the generator generates a D+ signal proportional to the engine speed, the starter generates a feedback signal for the starter motor action, the current sensor generates a current signal when the starter starts, and the starting relay controls the starting circuit On and off, the start button generates a start control signal.
[0026] The electrical integrated control box 2 is respectively connected with the start button 1, the generator 6, the start relay 3, the start current sensor 5 and the starter 4;
[0027] The starting current sensor 5 is connected to th...

The invention relates to a vehicle program starting control method. A control system of the method comprises a starting button, a control box, a starting relay, a starter, a starting current sensor and a power generator, wherein the control box is respectively connected with the starting button, the power generator, the starting relay, the starting current sensor and the starter; and the startingcurrent sensor is respectively connected with the starting relay and the starter. The invention can be used for accurately calculating the starting current and the engine D+ signal, has high control accuracy, can realize the automation of the starting process, can achieve the functions of starting time protection, D+ interlocking, overcurrent interlocking, starting times accumulation and the like, plays a role of protecting a starting motor and a storage battery, and can succeed in probation in starting control systems of a plurality of special vehicles.
Description
technical field [0001] The invention relates to a vehicle program start control technology, in particular to a vehicle program start control method. Background technique [0002] In present technology, the engine start of special vehicle mainly has two kinds of methods of electric start and compressed air start, and electric start has emergency start and procedure start again. Both compressed air starting and emergency starting are used in emergency situations. Program starting is a starting method under normal conditions. It is a starting method aimed at realizing the automation of the starting process and protecting the starter motor and battery. There is also program start on the previous special vehicles, but the function is relatively simple, and the control accuracy is low. There is no accurate calculation of the starting current and the generator D+ signal, and it can no longer meet the requirements of the new generation of special vehicles for program start. Conten...
