Composite joystick device used for controlling multi-degree-of-freedom novel ambulance vehicle

Abstract

The invention belongs to the technical field of vehicle control, and relates to a composite joystick device used for controlling a multi-degree-of-freedom novel ambulance vehicle. The composite joystick device replaces a steering wheel, an accelerator pedal, a braking pedal and gears of a traditional vehicle, a joystick installed at the left hand side of a driver is used for multi-mode steering of the vehicle and control of a multi-degree-of-freedom feedback energy suspension system, and a joystick installed at the right hand side of the driver is used for multi-mode driving of the vehicle and feedback energy brake control. Through multi-mode steering, the maneuverability of the ambulance vehicle in middle-low speed city crowded road conditions can be improved, and the quick and free movement in various directions is achieved; through multi-mode driving, driving and steering error tolerance functions of the vehicle are increased; through the multi-degree-of-freedom feedback energy suspension system, the vehicle body is maintained to be relatively horizontal all the time, enough comfort is brought to a patient who is delivered, and processed precise road sense can be fed back to the composite joystick device through steering, suspension, acceleration and braking, and thus the maneuverability of the vehicle is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile control, and more specifically, the invention relates to a composite joystick device for multi-degree-of-freedom novel ambulance control. Background technique [0002] Safety, energy saving and environmental protection are the development direction of today's automobiles. Electronic intelligence is an important means to achieve this direction. The wire control technology liberates the steering system from the traditional mechanical steering mechanism, and can realize four-wheel independent steering, independent drive, independent Chassis architecture with independently adjustable braking and suspension systems. [0003] This advanced wire-controlled car not only has the incomparable maneuverability of traditional vehicles, but also improves active safety by integrating the sensor information of the whole car and using the electronic control unit to judge and output instructions.

Problems solved by technology

At present, there are many types of suspensions, and most of the suspension systems used in ambulances have poor performance. Even if a more advanced active suspension system is used, the degree of freedom of active suspension adjustment is limited, and the adjustment has hysteresis. Larger roads have a great impact on the comfort of transported patients, and may even aggravate the patient's condition due to bumps
