When vehicle is arrived at via the driving path that path planning unit 20 is planned, the following parameters of motor 80 can be further limited
In at least one：Output power, driving current, driving voltage, maximum speed and peak acceleration make remaining electricity
It can obtain the utilization of bigger, electric vehicle can be driven to travel farther distance.
Step 70：Whether arrive atIf it is, carry out step 73；If it is not, then carry out step 63；
Step 72：Output charging is suggested, such as charging suggests it being the charging station charging to nearby.
Step 73：Terminate.
Electric vehicle is one kind in passenger car, two wheeler and tricycle.
The electrombile control method of present invention embodiment shown in Fig. 4, it is similar with Fig. 3, motor 80 can be adjusted in time
Drive mode, when necessary starter motor 80 battery saving mode, in addition to this, the difference lies in：Present embodiment can be with
Motor is controlled to drive electric vehicle with further battery saving mode, it is ensured that electric vehicle can arrive at.
Electric vehicle and its control device of the present invention and control method, if driver presses destination shortcut key or input
Whether destination, the course continuation mileage that control device can calculate remaining capacity automatically can make electric vehicle drive to destination, such as
It is necessary to then the battery saving mode of starter motor, makes battery pack in the case where electricity is limited to fruit, in the traveling for increasing electric vehicle
Journey ensures that electric vehicle arrives at as far as possible.If can not still arrive at, control device intelligently proposes to charge
Propose, so as to be effectively prevented electric vehicle in the process of moving because motor being made to be stopped during dead battery capability.
Although being described herein with reference to specific embodiment and describing the present invention, the scope of the present invention is not limited to
In shown details.In the case of without departing from the basic principle of the present invention, various modifications can be made for these details.
