Description

Technical Field

[0001] The present invention relates to the technical field of all-in-one controllers, and in particular to a highly integrated all-in-one controller for buses. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.

[0003] Existing new energy buses use controllers to intelligently control the vehicle's circuits. When the vehicle is in the summer season, the outside sunlight is strong and the temperature is high. In order to cool down, the driver often turns on the air conditioner in the car, which causes a temperature difference between the inside and outside of the window. If the air conditioner outlet blows directly into the window at this time, the window inside and outside will increase the chance of the window bursting due to the huge temperature difference. However, the existing controller lacks the function of the air conditioner outlet avoiding the window, which is not conducive to the normal use of the window. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem in the prior art that the controller lacks the function of avoiding the air-conditioning outlet to the window, which easily increases the probability of the window bursting due to the huge temperature difference between the inside and outside of the window, and proposes a highly integrated all-in-one controller for buses.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

The first inverter and the second inverter in the component S1 both convert direct current into alternating current and provide energy for the electric resistance steering system and the braking system respectively.

[0016] Preferably, the monitoring system in component S4 monitors the temperature at the window through a temperature sensor, and adjusts the wind direction of the air-conditioning outlet, the curtain of the skylight, and the opening and closing of the wipers according to the temperature at the window.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Reference Figures 1-4 , a highly integrated all-in-one controller for buses, including the following components:

[0032] Component S1: an all-in-one controller includes a DC-DC converter, a first inverter, and a second inverter, and controls the DC-DC converter, the first inverter, and the second inverter through the all-in-one controller, making the all-in-one controller a multifunctional controller;

[0033] Component S2: The DCDC converter includes a low-voltage control system, the first inverter includes an electric resistance steering system, and the second inverter includes a braking system; the DCDC converter in component S1 converts the high-voltage electricity of the vehicle's high-voltage battery pack into low-voltage electricity, and provides energy for the low-voltage control system to assist the normal operation of the low-voltage control system. The first inverter and the second inverter in component S1 both convert direct current into alternating current, and the first inverter and the second inverter provide energy to the electric resistance steering system and the braking system respectively to assist the normal operation of the electric resistance steering system and the braking system.

[0034] Component S3: Low-voltage control system including monitoring system and regulation system;

[0035] Component S4: Monitoring system includes light intensity sensor, temperature sensor and driver monitoring camera; adjustment system includes air conditioning vents, sunroof, sun visor and wipers;

[0036] In particular, when the vehicle is outdoors in the summer and the air conditioner is turned on, the monitoring system uses temperature sensors to monitor the temperature at each vehicle window. If there is a temperature difference between the inside and outside of the window, the control system adjusts the air flow direction of the air conditioner outlet to avoid the window from bursting due to the large temperature difference between the inside and outside of the window.

[0037] At the same time, when there is a temperature difference between the inside and outside of the window, the adjustment system closes the sunroof curtain to reduce the amount of external ultraviolet rays entering and improve passenger comfort. The adjustment system also activates the wipers to clear the water mist on the front window to prevent the water mist on the front window from affecting the driver's normal driving.

[0038] The monitoring system uses a light intensity sensor to monitor sunlight intensity, while a driver monitoring camera monitors whether the driver is squinting. If sunlight is strong and the driver is squinting, the system adjusts the sun visor to reduce the impact of strong sunlight on the driver, preventing the driver from being distracted by manually flipping up the sun visor, thereby reducing the chance of driving accidents.

[0039] Component S5: Electric resistance steering system includes sensor group, electronic control unit, power actuator and mechanical steering system;

[0040] Component S6: The sensor group includes a torque sensor and a vehicle speed sensor, the electronic control unit includes an EPS control module, the power actuator includes a power motor and a reduction mechanism, and the mechanical steering system includes a steering column, a universal joint, and a rack-and-pinion mechanism;

[0041] Preferably, the electric resistance steering system detects the steering wheel rotation torque and direction through a torque sensor, and the torque sensor is a non-contact Hall sensor, which is the core input signal of the electric resistance steering system. At the same time, the electric resistance steering system detects the vehicle speed signal through a vehicle speed sensor and uses it to dynamically adjust the electric power assistance to achieve lightness at low speed and stability at high speed.

[0042] Preferably, the electric resistance steering system calculates the required power assist size and direction through the EPS control module and outputs motor control instructions, while integrating fault diagnosis functions to determine faults such as motor overheating and signal abnormalities.

[0043] Preferably, the power-assist motor is mainly a brushless DC motor, which focuses on high efficiency and low noise. If it is a steering column power-assist type, the motor is installed on the steering column, which has a compact structure and is suitable for small cars; if it is a pinion power-assist type, the motor drives the steering gear, balancing performance and cost, and is the most widely used; if it is a rack power-assist type, the motor directly drives the rack, which has great power assistance and is used in medium and large cars / SUVs.

[0044] Preferably, the reduction mechanism is a worm gear or a planetary gear set to amplify the motor torque and transmit it to the steering system;

[0045] Preferably, the steering wheel and steering gear are connected via a steering column and universal joint to retain mechanical redundancy, thereby enabling manual steering in the event of electronic failure, while the rotational motion is converted into lateral motion of the wheels via a rack-and-pinion mechanism, which is the same as the mechanical structure of a fuel vehicle;

[0046] Component S7: The brake system includes traditional hydraulic brake components and electronically controlled core components;

[0047] Component S8: Traditional hydraulic brake components include the brake pedal, brake master cylinder, brake wheel cylinder and brake lines, and the core electronic control components include the electronic brake booster and electronic stability control unit.

[0048] Preferably, the brake pedal is the driver's input interface, and the driver's pedal force is input through the brake pedal. Some models are equipped with a wire-controlled pedal. In the intelligent driving mode, the pedal feel is simulated. At the same time, the braking system converts the pedal force into hydraulic pressure through the brake master cylinder, and the brake wheel cylinder allows the hydraulic pressure to push the brake pads to rub the brake disc. The brake line is a traditional hydraulic line, integrated with the anti-lock braking and body stability systems, and the wheel cylinder pressure is adjusted by the solenoid valve;

[0049] Preferably, the braking system replaces the traditional vacuum booster pump with an electronic brake booster. This is because new energy vehicles have no engine and cannot provide vacuum. At the same time, the pedal force is directly amplified by the motor to achieve faster response. The electronic brake booster supports brake energy recovery coordination and automatic driving active braking. The electronic stability control unit integrates ABS and TCS, and controls traction, while achieving precise braking force distribution through motors and sensors.

[0050] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
