Example Embodiment

[0024] The following describes the embodiments of the present invention in detail, but the present invention can be implemented in a variety of different ways defined and covered by the claims.

[0025] In some vehicles (such as large-tonnage all-terrain cranes, etc.), because the engine supporting manufacturers do not have a matching engine, or due to the matching engine installation size limit, or for energy saving considerations, dual power is usually used (first The main power source (first engine) is arranged in the first unit for driving the vehicle on smooth roads, and the auxiliary power source (second engine) is arranged in the second unit, It is used for vehicle uphill conditions or rough roads to provide auxiliary power for the first unit. The present invention provides an automatic control method and device for the realization of the main and auxiliary power source opening and closing and speed synchronization according to the road running conditions of the whole vehi...

Abstract

The invention provides a chassis drive system control method and device. The chassis drive system control method includes: judging a first engine is over-loaded or not according to stall rate of the first engine and/or judging whether an automobile slips or not according to slippage rate of the automobile; and controlling power output of a second engine under the condition of overload of the first engine and/or slippage of the automobile. According to driving road condition of the integral automobile, the second engine is automatically started and stopped, so that right switching time can be found, automatic matching of the first and second engines can be realized, operation fatigue of drivers is alleviated, automation degree of the integral automobile is improved, energy is more saved, and flameout caused by misoperation is avoided.

Description

technical field [0001] The present invention relates to the field of vehicles, and more specifically, to a control method and device for a chassis drive system. Background technique [0002] Such as figure 1 As shown, the chassis of the super-large tonnage all-terrain crane includes a first unit 1 and a second unit 2, wherein a first engine 3 is arranged in the first unit 1, and a second engine 4 is arranged in the second unit 2 . The crane is driven by the first engine 3 and the second engine 4 to travel on the road. The first unit 1 has a first drive axle 5 and a first non-drive axle 6 , and the second unit 2 has a second drive axle 7 and a second non-drive axle 8 . [0003] Among them, the first engine 3 is used as the main power to drive the whole vehicle to run on a smooth road, and the second engine 4 is used as the auxiliary power. Or personal perception, operate the manual button to switch. In the process of manual switching by the driver, it is difficult to gra...
