1 is a view showing a battery of an electric vehicle for explaining an embodiment of the present invention. The vehicle control apparatus and method of the present invention can be applied to a variety of electric / electronic (electronic) devices, such as an internal electric vehicle (ICV), a pure electric vehicle (EV), a hybrid electric vehicle Device.

As shown in Fig. 1, an electric vehicle 1 includes a battery 2 that supplies power to a motor. For example, a hybrid vehicle mounts a battery pack composed of a plurality of battery cells to receive a required power. A plurality of battery cells included in the battery pack need to uniformize the voltage of each battery cell in order to obtain safety, life span, and high output. The vehicle control device allows each battery to have an appropriate voltage while charging or discharging the batteries of the battery pack. On the other hand, in a battery management system, it is difficult to stably maintain the equilibrium state due to various factors such as a change in the internal impedance of the plurality of battery cells. Therefore, the battery management system has a balancing function for equilibrating the charged states of a plurality of battery cells.

For example, due to the difference in the self-discharge rate of the battery cells in the battery pack, there arises a difference in the state of charge (SOC) between the battery cells in the battery pack over time. In order to overcome the capacity imbalance between the battery cells, a separate circuit is provided to boost and / or buck the battery cells.

2 is a diagram showing a configuration of a hybrid electric vehicle for explaining an embodiment of the present invention. The vehicle control apparatus and method of the present invention are applicable not only to hybrid electric vehicles, but also to pure electric vehicles and general automobiles.

2, the hybrid electric vehicle includes an engine 101 and a motor / generator unit (hereinafter referred to as "M / G unit") 102 as a power source. The driven wheel driven by the power source is a front-wheel in a front-wheel drive vehicle and a rear-wheel in a rear-wheel drive vehicle. In the following, the all-wheel-drive vehicle will be described. The embodiment of the rear-wheel drive vehicle is apparent from the following description of the all-wheel-drive vehicle.

The M / G unit 102 is a device that selectively functions as a motor or a generator depending on the driving state, and is apparent to those skilled in the art. Therefore, in the following description, the M / G unit 102 can be used as a motor or a generator for the sake of understanding, but all refer to the same components. The engine 101 and the motor 102 of the electric vehicle are connected in series to a transmission.

The M / G unit 102 is driven by a signal of an inverter 104 under the control of a motor control unit (MCU) 103.

The inverter 104 drives the M / G unit 102 as a power source by using the electric energy stored in the battery 105 under the control of the MCU 103, G unit 102 to the battery 105 when the generator 105 is driven by the generator.

The power of the engine 101 and the M / G unit 102 is transmitted to the transmission (T / M) 107 via the clutch 106, and the final drive gear (F / R) 108 to the front wheels 109. [ The rear wheel 110 is a non-driving wheel that is not driven by the engine 101 and the M / G unit 102.

Each of the wheel brake units 111 is driven by an electric motor based on the hydraulic pressure generated by the operation of the brake pedal 112 and the brake pedal 112 so that the wheel brake unit 111 can be driven. And a hydraulic control system 113 for braking. The electric vehicle includes a brake control unit (BCU) 114 for controlling the hydraulic control system 113 and receiving a brake control state from the hydraulic control system 113, .

The BCU 114 detects the hydraulic pressure generated in the hydraulic pressure control system 113 when the brake pedal 112 is operated by the driver. Based on this, the BCU 114 calculates a braking force to be applied to a drive wheel (for example, the front wheel 109), a hydraulic braking force to be braked by the intermediate hydraulic pressure, and a regenerative braking force to be braked by regenerative braking. The BCU 114 supplies the calculated hydraulic braking force to the wheel brake unit 111 of the front wheel 109 through the control of the hydraulic pressure control system 113. [

The electric vehicle is a hybrid electric vehicle electronic control unit (ECU) implementing an electric vehicle that communicates with and controls the BCU 114 and the MCU 103 to perform a maximum speed limiting method. (Hereinafter referred to as "HEV-ECU"

The regenerative braking force calculated by the BCU 114 is transmitted to the HEV-ECU 115 so that the HEV-ECU 115 controls the MCU 103 based on the received regenerative braking force. Accordingly, the MCU 103 drives the M / G unit 102 as a generator so that the regenerative braking force designated by the HEV-ECU 115 is realized. At this time, the electric energy generated by the M / G unit 102 is stored in the battery 105.

The electric vehicle further includes a vehicle speed detector (116) for detecting a vehicle speed.

The HEV-ECU 115 utilizes the vehicle speed detected by the vehicle speed detector 116 as data for controlling the BCU 114 and the MCU 103.

The electric vehicle further includes a battery voltage detector 117 for detecting a voltage of the battery 105. [ The battery voltage detector 117 detects the current voltage of the battery 105 and controls the HEV-ECU 115 to limit the maximum speed of the electric vehicle according to a deviation between the detected current voltage and a preset reference voltage Provide the resulting data to enable.

On the other hand, an electric vehicle uses a battery to drive a motor, and the lifetime of the battery is an important part in an electric vehicle. The battery voltage of the battery cell changes slightly over time. This imbalance is one of the important factors to reduce battery life. Most electric vehicles must continuously perform cell balancing in order to prevent imbalance between these cells and to prolong the life of the battery. The cell balancing is a method of connecting a small load to a battery cell having a high voltage and discharging the current to equalize the voltages with other cells.
