Description
VEHICLE MANUAL BRAKE AUXILIARY SYSTEM
1. Field of the Invention
The present invention relates to a vehicle manual brake auxiliary system, and more particularly to a vehicle manual brake auxiliary system to automatically stop movement of the vehicle when the driver is not at the driver's seat and the manual brake is not engaged.
2. Description of Related Art
Automobiles regardless of stick-shift gear change type or the automatic type are introduced to the world to bring fast paced lifestyle and convenience to the people.
Distance seems not to be a problem between two persons far away from each other because of the convenient transportation opportunities we now have.
However, despite all the conveniences we have in our lives due to the introduction of cars, there is still something which is not so convenient to the user (the driver). That is, whenever the car is stopped, the driver has to apply the manual brake before leaving the car, otherwise, the car will move due to the slope of the road. If the driver forgets to apply the manual brake, the car might be damaged or even endanger a passersby. This kind of danger originates from the total dependence to the driver's concern to safety and the danger arising from a driver's forgetfulness is not addressed.
To overcome the shortcomings, the present invention tends to provide an improved auxiliary braking system to mitigate the aforementioned problems.
The primary objective of the present invention is to provide an improved vehicle manual brake auxiliary system to automatically stop the vehicle from movement when the driver is not in the driver's seat.
In order to accomplish the foregoing objective, the system of the present invention includes the following elements: a controlling unit to receive and analyze signals indicating the current car status and whether the driver is away from the car so as to initiate necessary actions; a pressure sensor received in the driver's seat to sense the pressure from the driver and then send a signal to the controlling unit to determine whether the driver is at the driver's seat; a speed interface to communicate an input of the controlling unit with a vehicle speed sensor (VSS) to allow the controlling unit to acquire a speed signal as a reference for determination of whether the car is in movement; and a server mechanism to mechanically control the braking system via a motor under the control of the controlling unit, whereby when the car is detected to be motionless, the driver is also detected to be away from the driver's seat and the manual braking lever is not engaged by the driver, the server mechanism under the command of the controlling unit will then initiate the motor to engage the braking system to secure the car to as to accomplish the purpose of stopping the movement of the car and prevention of accidents.
A further advantage of the invention is that the controlling unit has a pushbutton operably connected to the controlling unit to allow the driver to manually engage/disengage the braking system.
Another advantage of the present invention is that the controlling unit further monitors whether the braking pedal is engaged and whether the ignition system is off so as to engage the braking system under the circumstances that the braking pedal is engaged and the vehicle ignition system is off.
Still, a further advantage of the present invention is that the auxiliary system further has an indicator operably connected to an output of the controlling unit to send either visually or acoustically a signal to the driver.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
In the drawings: Fig. 1 is a block diagram of the auxiliary system of the present invention; Fig. 2 is a schematic view showing the possible locations inside a vehicle to mount the auxiliary system of the present invention; and Fig. 3 is a circuit diagram of the auxiliary system of the present invention, wherein Fig 3 is divided into three sub-diagrams, Fig. 3A, 3B and 3C.
With reference to Fig. 1, the vehicle manual brake auxiliary system in accordance with the present invention includes: a controlling unit (10) to receive and analyze signals such as the current car status and whether the driver is away from the car so as to initiate necessary actions; a pressure sensor (11) received in the driver's seat (as shown in Fig. 2) to sense the pressure from weight of the driver and then send a signal to the controlling unit (10) to determine whether the driver is at the driver's seat; a speed interface (12) to communicate an input of the controlling unit (10) with a vehicle speed sensor (VSS) to allow the controlling unit (10) to acquire a speed signal as a reference for determination of whether the car is in movement; an indicator (13) operably connected to an output of the controlling unit ( 10) to provide a visual or acoustic signal showing the current vehicle status to the driver; a pushbutton (14) operably connected to an input of the controlling unit (10) to allow the driver to selectively engage/disengage the brake system; and a server mechanism (15) to mechanically control the brake system via a motor under the control of the controlling unit (10). When the car is detected to be motionless, the driver is also detected to be away from the driver's seat and the manual braking lever is not engaged by the driver, the server mechanism ( 15) under the command of the controlling unit (10) will then initiate the motor to engage the brake system to secure the car to as to accomplish the purpose of stopping the movement of the car and prevention of accidents.
The controlling unit (10) is able to receive and analyze the information about whether the driver is at the driver's seat and whether the vehicle ignition system is ON or OFF as a reference for determination of the vehicle current status.
With reference to Fig. 3 and Figs. 3A, 3B and 3C, the controlling unit (10) is composed of a microprocessor (8951). Inputs of the controlling unit (10) respectively connect to the speed interface (12), the indicator (13), the pushbutton (14) and the server mechanism (15).
The pressure sensor (12)is connected to the controlling unit (10) via a connection interface circuit (111). An input of the speed interface (12) is connected to the vehicle's VSS and an output of the speed interface (12)is connected to the controlling unit (10). The indicator (13) is composed of a display (131) and a buzzer (132) respectively connected to the output of the controlling unit ( 10) so that the driver is reminded by either visual or acoustic signals or the combination thereof of the current vehicle status.
Two inputs of the controlling unit (10) are respectively connected to two switches (16,17) to sense whether the brake lights of the vehicle are ON to determine s whether the brake pedal is engaged and whether the ignition system is ON. The server mechanism (15) is connected to the vehicle's onboard brake system which in turn is able to send a signal to the controlling unit (10) to indicate the current status when the onboard brake system is already engaged.
According to the aforementioned description, it is said that when the VSS signal is detected by the controlling unit (10) to be zero (0), the vehicle is motionless, and the pressure sensed by the pressure sensor (14) is also zero (0), the driver has left the driver's seat, the controlling unit (10) will send a signal to engage the onboard brake system via the server mechanism ( 15) to ensure that the vehicle is not movable when the onboard brake system is not engaged.
Furthermore, when the driver is still sitting on the driver's seat (the pressure sensor (14) senses a pressure), the brake lights are ON (the brake pedal is stepped down to engage the onboard brake system) and the ignition system is OFF, the controlling unit (10) may still be able to engage the onboard brake system via the server mechanism (15) to prevent movement ofthe vehicle. Meanwhile, the display (131) or the buzzer (132) of the indicator (13) is able to send out a picture or a warning alarm to remind the driver of the engagement of the onboard brake system.
If the vehicle is detected to be motionless and the brake pedal is stepped down, the auxiliary system of the present invention is in a standby status. In the meantime, the controlling unit (10) continues to monitor the status of the pushbutton (14). If the pushbutton (14) is pressed, the auxiliary system switches from one mode to the other mode. For example, if the auxiliary system is already engaged before the pushbutton (14) is pressed, the downward movement of the pushbutton ( 14) will disengage the locking mode of the onboard brake system to the vehicle. However, if the auxiliary system is not engaged before the pushbutton (14) is pressed, the downward movement of the pushbutton (14) will initiate the controlling unit (10) to enter a monitoring mode and the indicator (13) to indicate the current status of the auxiliary system.
Still, if the vehicle is already in motionless status and the auxiliary system is engaged, if the pushbutton ( 14) is pressed more than a predetermined time period (e.g. seconds), the auxiliary system will automatically disengage the onboard brake system no matter what the current vehicle situation is and the indicator (13) will display the disengagement status of the auxiliary system, which applies only when there is a malfunction in the vehicle and the driver is at the driver's seat.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
