Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a driving operation warning device for more economical vehicle travel. Nowadays, resource conservation is being sought in all aspects.
Since the amount of fuel consumed by automobiles also accounts for a considerable proportion, efforts are being made day and night to develop automobiles that are as fuel efficient as possible. However, no matter how much the fuel efficiency of automobiles has been improved, depending on the driving conditions, it is not always possible to achieve fuel economy. In other words, fuel economy can only be achieved by using a driving method that matches engine performance and power transmission system specifications, and by eliminating driving operations that waste fuel during driving. In general, driving methods that improve fuel efficiency include: (1) Driving in a higher shift position. (2) Drive at economical speed. (3) Shift up early and downshift late. (4) Avoid sudden stops or overusing the brakes, and coast. (5) Do not start or accelerate suddenly. (6) Stop running in waves and run at a constant speed. (7) Do not make empty calls. By taking these matters into consideration, effective fuel savings can be achieved. Techniques for generally economical vehicle operation have already been proposed, and are also described, for example, in Japanese Patent Laid-Open No. 7722/1983. However, in this technique, economical driving is determined by detecting the engine load, that is, the intake load, and the engine rotation speed, and therefore, no determination is made on the shift stage or brake operation. For that purpose, the above (1)
(7) cannot be satisfied. Therefore, an object of the present invention is to provide a driving operation warning device that can satisfy the above requirements. The driving operation warning device according to the present invention includes detection means for detecting engine speed, engine load, vehicle speed, acceleration/deceleration, and shift position, and detects the engine speed, engine load, acceleration, and final shift position for each shift stage. The maximum speed and deceleration are set respectively, and based on the signals detected by the respective detection means, when the engine speed during acceleration exceeds the set value set for each shift stage, the engine load is becomes below the set value set for each shift stage, when the acceleration suddenly exceeds the set value for each shift stage, or when decelerating suddenly exceeds the set deceleration rate during deceleration.
During steady running, when the load falls below a set value set for each shift stage, and when the vehicle speed exceeds the set maximum speed at the final shift stage, a warning means is provided that issues various warnings. Vehicle running can be roughly divided into three categories: acceleration, steady state, and deceleration, and the device is set so that some of the above items can be satisfied for each of them. If the set value is exceeded, the driver is able to perform appropriate driving operations by displaying an indication using a lamp, buzzer, chime, etc., in case the set value is exceeded. By using appropriate setting values, it is possible to establish in the driver the optimum conditions that lead to fuel efficiency. The table below shows the setting items and driver countermeasures. [Table] Drivers are warned not to revitalize as other revving is also uneconomical driving. If this is simplified further, the flow will be as follows, and it is possible to implement driving situation detection, comprehensive judgment, and display. [Table] FIG. 1 shows a flowchart of the apparatus of the present invention. By starting the engine 1, a counter 2 is cleared to zero position, and a driving time counter 3 counts and displays the driving time. The engine load is detected by an accelerator opening detection device 4, etc., and the engine rotation speed is detected by an engine rotation speed detection device 5, and the result is integrated by a rotation speed totalizer 6 and displayed.
Furthermore, the vehicle speed is detected by a vehicle speed detection device 7. The detected vehicle speed, engine rotation speed, and accelerator opening degree are input into the minimum speed determination device 8, the minimum rotation speed determination device 9, and the minimum accelerator opening degree determination device 10, respectively, and the set minimum vehicle speed, minimum engine rotation speed, and minimum If it is less than the accelerator opening, it is considered as economical driving (eco-run driving) and is inputted into the eco-run mileage accumulator 24 according to the bold line, which is integrated and displayed, and the OK lamp 25 is turned on.

to detect the shift position. If it is the final gear shift 13, the mileage totalizer 14 adds up the mileage and displays it, and the maximum speed determination device 15 determines the vehicle speed at that time. The non-eco-run mileage is input into the non-eco-run mileage accumulator 26 according to the thin line shown as non-eco-run driving, and is integrated and displayed.
The NG lamp 27 flashes and a chime sounds to warn the driver to drive at an economical speed. Also, if the shift position is neutral 16 and the accelerator opening is equal to or higher than the set minimum opening, it will be idling, and it will be input to the non-eco-run mileage totalizer 26 according to the thin line as non-economical driving (non-eco-running driving). The NG lamp 27 flashes and a chime sounds to warn the driver not to overdrive. If the shift position is the final gear shift and is below the set maximum speed, or if it is not the final gear shift and is not neutral, it is determined whether appropriate acceleration or deceleration is being performed. The acceleration determination device 17 determines the acceleration, and if the acceleration is within the set acceleration ±α/g, that is, the engine speed is normal, the engine load is determined by the maximum accelerator opening determination device 18, and the set maximum accelerator opening is determined. If this is the case, the eco-run mileage is entered into the eco-run mileage accumulator 24 according to the thick line as an economical run (eco-run run), and is integrated and displayed, and the OK lamp 25 is turned on. In addition, if the following is true, it is considered non-economical driving (non-eco-running driving) and the non-eco-running mileage totalizer 2 follows the thin line.

The NG lamp 27 flashes and a chime sounds to warn the driver to shift to the upper gear. If the acceleration is equal to or greater than the set acceleration ±α/g, the sudden acceleration distance integrator 19 integrates and displays it, and the acceleration/deceleration determination device 20 determines whether it is acceleration or deceleration. If the vehicle is decelerating, the eco-run driving or non-eco-running driving is integrated and displayed in the same manner as in the case of steady driving, and the OK lamp is turned on or the NG lamp is flashed. In case of acceleration, ○…
