Abstract
The utility model discloses an automatic adjusting device for side tilting angles of an automobile body based on an ECU (electronic control unit) in the automobile steering process. The device comprises a tilting angle sensor, an automobile-mounted computer ECU and executors, wherein the executors comprise air spraying devices and an air compressor. The tilting angle sensor is used for detecting a side tilting signal of the automobile body, the signal is inputted into the ECU and is analyzed and processed by the ECU, then an executing instruction is outputted to the executors, air valve opening size control devices in the air spraying devices at the left side and right side of the automobile body receive the instruction outputted by the ECU to respectively and automatically control the opening sizes of valves, then by controlling the volume of the sprayed air, the size of the action force applied to the left end and right end of an automobile is controlled, and finally, the side tilting angle of the automobile body is automatically adjusted by utilizing the action of torque which is generated by the thrust size of the air sprayed at the left side and right side of the automobile body.
Description
Technical field
The utility model relates to motor turning and ride safety of automobile field, specifically, relate to a kind of based on ECU automatic compensation vehicle roll angle automatic regulating apparatus, to guarantee the motor turning driving safety.
Background technology
Automobile is turning to when travelling, and the bank moment that the vehicle body centnifugal force causes can make vehicle body outward-dipping, produces angle of roll, and suitable angle of roll can improve the riding stability and the ride comfort of automobile.But crossing conference, angle of roll make chaufeur feel that unstable, dangerous, vehicle body takes place to break away even cause horizontal roll-over accident.At present, most of automobiles utilize level indicator to overcome the above problems more, automobile-used level indicator, its main effect is that the angle that can monitor automobile inclination angle, the elevation angle and vehicle body left rotation and right rotation at any time changes, directly clearly illustrate the residing horizontality of vehicle body, the information of relevant traffic safety is provided timely and accurately for the car owner.But this device has just played reminding effect, and does not make corresponding effectively measure of control.Angle from road-holding property and safety performance, when vehicle roll angle is very big, must apply an external force and produce a moment opposite with the bank moment direction, reduce the angle of roll of vehicle body, the vehicle roll angle self-checking device is realized above-mentioned functions when therefore, specially designing motor turning.
Summary of the invention
The purpose of this utility model is, vehicle roll angle self-checking device when a kind of motor turning based on ECU is provided, this device can detect the inclination situation of automobile in real time, in time it is made remedial measures when angle of roll is excessive, make that vehicle roll angle always keeps suitable value when turning to, improve the riding stability and the safety of automobile.
In order to realize above-mentioned technical assignment, the utility model adopts following technical scheme to be achieved:
Vehicle roll angle automatic regulating apparatus during a kind of motor turning based on ECU, it is characterized in that, comprise obliquity sensor, vehicle-mounted computer (ECU) and actr, wherein, described actr comprises two gas injection apparatus and an air compressor, gas injection apparatus is positioned on the drive axle of wheel both sides, and air compressor is below the vehicle body lower shoe and the bottom half between the drive axle;
Air compressor is connected with gas injection apparatus, and obliquity sensor is connected with the input circuit of vehicle-mounted computer, and gas injection apparatus is connected with the output loop of vehicle-mounted computer.
Other characteristics of the present utility model are:
Described gas valve opening control device is positioned on the gas injection apparatus.
Vehicle roll angle automatic regulating apparatus during the motor turning based on ECU of the present utility model, compared with prior art, the technique effect that brings is:
1, when vehicle roll angle is excessive except basic prompting function is arranged, the size of control automatically regulating angle of roll that can also be by ECU has improved stability and safety.
2, simple in structure, cost is low, for ease of maintenaince, practicality is good.
Description of drawings
Vehicle roll angle self-checking device circuit structure block diagram when Fig. 1 is the motor turning based on ECU of the present utility model.
The vehicle roll angle self-checking device was arranged scheme drawing when Fig. 2 was the motor turning based on ECU of the present utility model.
Mark among the figure is represented respectively: 1, vehicle body lower shoe, 2, spring, 3, wheel, 4, drive axle, 5, vehicle-mounted computer (ECU), 6, obliquity sensor, 7, air compressor.8, casing, 9, gas injection apparatus, 10, the gas valve opening control device.
Below in conjunction with drawings and Examples the utility model is further specified.
The specific embodiment
The principle that the utility model adopts is that body roll during motor turning, angle of roll equal the ratio of bank moment and suspension angular rigidity, under the situation that suspension rate is determined, reduce the value that bank moment can reduce angle of roll.Produce the moment opposite and reduce angle of roll by apply power to vehicle body with bank moment.
See figures.1.and.2, the vehicle roll angle automatic regulating apparatus comprised obliquity sensor 6, vehicle-mounted computer 5(ECU when present embodiment provided a kind of motor turning) and actr, wherein actr comprises gas injection apparatus 9 and air compressor 7.Gas injection apparatus 9 is positioned on the drive axle 4 of wheel 3 both sides, and air compressor 7 is in 8 bottoms of the casing below the vehicle body lower shoe 1 and between the drive axle 4.
The annexation of various piece is: obliquity sensor 6 and vehicle-mounted computer 5(ECU) input circuit be connected, gas injection apparatus 9 and live brain 5(ECU in the actr) output loop be connected.Obliquity sensor 6, when vehicle body does not have the inclination level, also return to zero in the bottom that obliquity sensor 6 is fixed on casing 8, and the analog signal of obliquity sensor 6 acquisitions afterwards is the angle signals between casing 8 base plane and the horizontal surface; Vehicle-mounted computer 5(ECU) receives the signal of obliquity sensor 6 inputs and it is carried out computing, processing, judgement, then to actr output execution command.Air compressor 7 in the actr is connected with gas injection apparatus 9 and gas valve opening control device 10 is opened, for gas injection apparatus 9 provides high pressure gas continuous, capacity.
During motor turning, vehicle body run-off the straight under the bank moment that centnifugal force produces, the obliquity sensor 6 that is fixed on casing 8 bottoms is with the analog signal input vehicle-mounted computer 5(ECU that records), at vehicle-mounted computer 5(ECU) inside carries out digital to analogy conversion, computing, handle, judge, then executive command is exported to the gas valve opening control device 10 in the gas injection apparatus 9 of both sides, gas valve opening control device 10 is regulated the aperture size of two gas valves respectively according to command signal, thereby the amount by high pressure gas that control sprays is controlled the size that applies application force to the vehicle right and left two ends, this power produces the moment opposite with the bank moment direction, reduce excessive angle of roll, make angle of roll always keep suitable size, guarantee motor turning safety.
Used components and parts are commercially available known product in the device of the present utility model, and those skilled in the art can realize the connection of each components and parts according to the application's technique effect.
