Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] figure 1 In the schematic block diagram of the system, the power module conversion module in the vehicle controller connects the 12V DC power supply external to the controller through the DCDC conversion circuit to supply power to the sensors and sampling circuits connected to the controller; the composition of the switch is mainly It is composed of braking signal, gear signal, 12V power supply signal and ignition signal; the other part is composed of sampling circuit and instrument display module.

[0027] Analog linear sampling mainly includes power battery voltage sampling, power battery pack bus current sampling, and accelerator signal sampling. The power battery voltage is 48V / 72V, and the voltage must be converted into a 0-5V signal to be input to the microcontroller for AD conversion. Therefore, the system voltage sampling needs to be divided a...

Abstract

The invention provides an instrument display system of a purely electric field vehicle, which comprises a display controller module, a power supply module, a switching value collection module, an analog quantity collection module and a display instrument; the input end of the switching value collection module is respectively connected with an entire vehicle gear signal, an accelerator microswitch signal, a brake signal and an ignition switch signal; after the switching value collection module is isolated by a photoelectric coupler, the collected entire vehicle gear signal, the collected accelerator microswitch signal, the collected brake signal and the collected ignition switch signal are input into the display control module; the analog quantity collection module uploads a collected dynamic battery voltage signal, a collected dynamic battery bus current signal and a collected accelerator signal to the display control module; and the display control module is used for displaying the electric quantity of a dynamic battery, the voltage of the dynamic battery, the bus current of the dynamic battery, a drive motor of the entire vehicle and electric indication signals of low voltage of 12V and high voltage of 48V. The invention solves the monitoring display of the faults of the battery, the motor and the system and provides greater guarantee for the safety of driving and the reliability of the system.

Description

technical field [0001] The invention belongs to the technical field of parts and components for pure electric track vehicles, and in particular relates to an instrument display system for pure electric track vehicles. Background technique [0002] The existing instrument display system of an electric field vehicle is to display the collected signal in the instrument through a driving circuit. The display system in the prior art has only shown simple signals such as vehicle speed, rotating speed, and indicator lights. However, some signals that affect driving safety, monitor the running state of the vehicle, and affect the driver's manipulation are not displayed in the instrument. The instrument display system disclosed by the invention is intended to solve the monitoring and display of battery, motor and system faults, and provide greater guarantee for driving safety and system reliability. Contents of the invention [0003] Aiming at the deficiencies of the prior art, a...
