Abstract

PURPOSE:To obtain stable fixed-speed car traveling by increasing the horsepower, when horsepower needs to be increased while a car is traveling at an fixed speed by means of an overdrive, by making the throttle opening larger and by cutting the overdrive to the downshift after the opening becomes larger than the specified one. CONSTITUTION:In a state of fixed-speed traveling, the output signal from a self- supporting circuit 120 reads ''H'' while a hydraulic switch 102 is turned ON to set the operation at the outdrive. When the car speed is lowered on a slope, a fixed-speed traveling unit operates to make an actuator increase the throttle valve opening. When the opening becomes larger than the specified one, a throttle sensor 80 produces a signal ''H''. Accordingly, the output from an AND circuit 110 turns from ''L'' to ''H'', and a normal close relay 210 is opened, suspending electrification to a solenoid 103. As a result, the overdrive is cut to be downshifted to the third gear. With this contrivance, the horsepower of the car can be increased for quick acceleration.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a constant speed running device for a vehicle, particularly to a Q+ constant speed running device equipped with an automatic transmission with overdrive.

Conventionally, automatic constant-speed running devices with overdrive use overdrive to lower the short range when running at a constant speed when the vehicle approaches the main road or the uphill road, which corrects the speed difference that occurs between the set vehicle speed and the vehicle speed. Adjust the opening of the throttle valve as much as possible.
Create an actuator to f[D+ and increase the opening degree of the throttle valve.

However, since the engine speed is generally low during overdrive, even if the throttle valve opening is increased, the horsepower is insufficient and the vehicle speed gradually decreases. In addition, the 7 kunayuator of the constant speed traveling device reduces the throttle valve opening to 0.
It is set to control about 60%. Therefore, in a constant speed traveling system, it is not possible to open the throttle valve beyond a certain level, and the deceleration becomes even greater.

Here, the control of the overdrive phrase automatic is based on the state of the engine output and the NiI! carried out by 1
],ing. This engine output state is determined by converting the throttle valve opening into a hydraulic signal, and the vehicle speed is converted into a hydraulic signal by a governor that rotates integrally with the rear end shaft. Kon
The transmission automatically shifts gears in response to these addition signals. Therefore, while driving in overdrive, m
The speed does not decrease and 7L is automatically downshifted to 8th gear.γ1. However, since the set speed of this downshift is set low for practical purposes, the horsepower will not be restored when the downshift is started.
It takes quite a while to reach T. For this reason, there is a drawback that the vehicle speed is significantly different from the set vehicle speed when driving at a constant speed.Therefore, the invention is to cut off the overdrive when horsepower is required while driving at a constant speed with overdrive. By downshifting to 3rd gear, the aim is to quickly gain horsepower.

The gist of the configuration is to cut the overdrive and downshift when the shift is more than that.

Therefore, according to the present invention, the 71 can automatically downshift to increase the horsepower when the horsepower is insufficient on a boarding road, etc., so that a stable constant speed running function can be obtained. In addition, when operating the resume fl function (a function that resumes constant speed driving once canceled), downshifting allows for smooth acceleration and the ability to return to constant speed driving in a short time. .

In the 0 constant speed running condition, the operation of which will be explained next, the output of the self-holding circuit is the Lr'H' level signal. Then, the oil pressure switch 102 is turned on and the transmission is in overdrive. At this time, when the vehicle speed decreases as Kawamuka approaches the boarding road, etc., the constant speed traveling position H is activated and the actuator 70 increases the throttle valve opening degree. When the throttle valve opening exceeds a predetermined value, the throttle sensor 80 generates a '11 level signal. Therefore, the output of the AND circuit 110 rises from the 'L level to the 'H level', opening the normally closed relay 210 and cutting off the current supply to the solenoid 103. Therefore, the overdrive is cut off and the vehicle downshifts to 3rd gear. Therefore, the main image can gain horsepower and accelerate quickly.
