Embodiment Construction

[0015] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0016] As a first aspect of the present invention, an accelerator control device is provided. Such as image 3 As shown, the accelerator control device includes: a pedal accelerator sensor 10, which is used to generate a first signal; a manual accelerator sensor 20, which is used to generate a second signal; For the current gear, use one of the first signal or the second signal as the throttle control signal. Preferably, when the current gear is the forward gear 41 or the reverse gear 42, the signal selection unit 30 uses the first signal as the throttle control signal, of course, the forward gear 41 and the reverse gear 42 may each include a plurality of sub-gears bit. Preferably, when the current gear is the neutral gear 43, the signal selectio...

Abstract

The invention provides an accelerator control device, an accelerator control method and an accelerator control engineering vehicle. The accelerator control device comprises a pedal accelerator transducer for generating a first signal, a manual accelerator transducer for generating a second signal, and a signal selecting unit which uses the first or second signal as the accelerator control signal according to the gear of the vehicle and the current gear of the handle. Through the signal selecting unit, automatic switching between pedal accelerator and the manual accelerator according to the gear of the vehicle is realized, so as to prevent or reduce the foot fatigue of the driver. Moreover, the accelerator control device of the invention has the characteristics of simple structure, low cost, and high reliability.

Description

technical field [0001] The invention relates to the field of vehicle control, more specifically, to an accelerator control device, method and engineering vehicle. Background technique [0002] With the widespread use of rough terrain cranes in China, the electronic accelerator pedal (also known as the pedal accelerator) has become a common way to control the engine speed at present. Restricted by the use occasions and conditions of the off-road tire crane, the operator needs to use the foot pedal for a long time to work, which is easy to cause fatigue to the operator. [0003] figure 1 A schematic diagram of a pedal accelerator in the prior art is shown. Such as figure 1 As shown, the pedal accelerator in the prior art is provided with a pedal accelerator sensor 10 (for example, it can be a Hall element, etc.), and the input terminals of the pedal accelerator sensor 10 are respectively connected to + of the internal power supply of the engine control unit (ECU). 5V and 0...
