Fig. 5 is the guidance panel scheme drawing of according to an embodiment of the invention electric-control system.According to one embodiment of present invention, by engine electric-controlled system, provide the selection of different power/economy balance to chaufeur, reach the purpose that reduces Fuel consumption.For example, chaufeur can switch in different choice by the operating switch on the operation operator's compartment wainscot, inputs thus desired running state, thereby makes the running state of electric control system controls driving engine.
As shown in Figure 5, be provided with three location options on the guidance panel of this electric-control system, power, standard and economy.That is to say that the electric-control system guidance panel provides three kinds of mode of operations.Chaufeur to different positions, just is set to different mode of operations corresponding to driving engine with switching toggle.
Selecting in the situation of " power ", electric-control system does not apply restriction to driving engine, and this is so that the driver can the as required running of control engine in the maximum design power scope of driving engine, with travelling of operating and controlling vehicle.
Selecting in the situation of " economy ", electric-control system applies maximum restriction to driving engine, for example, preferably, limits the engine speed of each gear, non-speed of a motor vehicle when the most high-grade of vehicle, and the moment of torsion of driving engine and acceleration/accel, and the maximum speed of vehicle.Certainly, this only is a kind of mode wherein, can also adopt other limiting mode, for example, limits non-one of speed of a motor vehicle when the most high-grade of the engine speed of each gear and vehicle; And the moment of torsion of driving engine, acceleration/accel, and this thrin of the maximum speed of vehicle, etc.
Selecting in the situation of " standard ", electric-control system applies to a certain degree restriction to driving engine, for example, limits the rotating speed of driving engine of each gear and the vehicle non-speed of a motor vehicle or one of them when the most high-grade.In the situation of " standard ", electric-control system is less than the restriction that in " economy " situation driving engine is applied to the restriction that driving engine applies.
Certainly, the mode of the corresponding restriction to driving engine of the diverse location of this switch only is a kind of schematic mode, obviously can also adopt multiple different array mode.Can find out, the different options correspondence of switch the various combination of a plurality of energy-saving functions.
Can select suitable driving model according to travel road conditions and vehicle load according to electric-control system of the present invention, below table 1 drive suggestion for chaufeur provides.
Table 1
| Smooth high speed | At a high speed uneven | Smooth national highway | Uneven national highway | |
