Problems solved by technology

[0006] However, in the conventional technology, the voltage value applied from the battery is not constant and fluctuates depending on the state of the vehicle
[0007] At this time, for example, when a high voltage higher than the rated voltage of the sensor is applied, a regulator (regulator) can be used to perform pressure reduction control to ensure a voltage value conforming to the rated voltage of the sensor. However, when a voltage lower than the rated voltage of the sensor is applied With low voltage, the sensor does not function properly, for example, the sensor is a little hard to operate causing the input voltage to be ignored

Abstract

Disclosed are a system and method for controlling a voltage of a vehicle. The system includes a battery voltage measurer configured to measure the voltage of a battery of the vehicle, a sensor driver configured to supply a voltage applied from the battery to various sensors included in the vehicle, and a controller configured to decrease or increase the voltage applied form the battery to secure a required voltage value required by the sensor driver.

Description

technical field [0001] The present invention relates to a voltage control method and its control system, and more specifically, to a voltage control method and its control system for supplying a constant voltage required by a sensor used in a vehicle. Background technique [0002] In general, the voltage value of a battery mounted on a vehicle is not constant but fluctuates depending on the state of the vehicle. [0003] However, the electronic control unit (Electronic Control Unit, ECU) included in the vehicle needs to secure a voltage value from the battery that matches the rated voltage of the sensor in order to operate normally. [0004] For example, when the vehicle performs brake-by-wire, the electronic control unit can calculate the control pressure required for proper brake-by-wire based on sensor values ​​measured by wheel speed sensors, wheel pressure sensors, and the like. [0005] In this case, it is necessary to secure a voltage value from the battery correspon...
