Definitions

  • the present invention relates to vehicle safety systems.
  • Vehicles incorporate many different types of safety systems for preventing or deterring a dangerous condition from occurring.
  • a vehicle may have an audible alarm that activates if a driver removes a key from the ignition while the vehicle is still engaged in an out-of-park condition. This provides notification to a driver that the vehicle is capable of moving since the transmission is not in a park position.
  • a method for deterring undesired movement of a vehicle.
  • An out of a park position of a vehicle transmission is sensed.
  • a non-presence of a driver in a driver seat of a vehicle is determined by an occupant detection system in response to the vehicle transmission being out of the park position.
  • An imminent movement of a vehicle is determined in response to determining the non-presence of the driver.
  • a vehicle movement prevention device is actuated for preventing movement of the vehicle in response to determining imminent movement of the vehicle.
  • a movement prevention system for a vehicle.
  • a transmission gear sensor senses an out of park position of a vehicle transmission.
  • An occupant detection system senses a presence of a driver in a driver seat of a vehicle in response to the vehicle transmission being out of the park position.
  • a processor determines an imminent movement of a vehicle in response to a determination of the non-presence of the driver.
  • a vehicle movement prevention device prevents movement of the vehicle in response to the processor determining imminent movement of the vehicle. Imminent movement is identified as actual movement of the vehicle or movement of the vehicle likely to occur.
  • an out of park position of a vehicle transmission is sensed.
  • a non-presence of a driver in a driver seat is determined by an occupant detection system in response to the sensed out of park position.
  • An imminent movement of a vehicle is determined in response to determining a non-presence of the driver.
  • a vehicle movement prevention device is actuated for preventing movement of the vehicle in response to determining imminent movement.
  • FIG. 1 is a block diagram of a vehicle movement prevention system.
  • FIG. 2 is a block flow diagram of a method for deterring undesired movement of a vehicle.
  • FIG. 1 is a block diagram of a vehicle movement prevention system 10 .
  • the system 10 includes a processor 12 for identifying conditions that are present which indicate imminent movement of a vehicle.
  • the processor 12 may be a standalone processor or may be an integrated processor that is used to control one or more vehicle systems. Imminent movement as used herein is defined as actual movement of the vehicle or movement that may occur as a result of the transmission gears being out of a park position and the driver of the vehicle is not seated in the driver seat.
  • the system 10 further includes an occupant sensing system 14 , at least one vehicle movement indication device 16 , and vehicle movement prevention devices 18 .
  • the processor 12 is preferably an in-vehicle processor. Alternatively, the processor 12 may be a remote processor which is part of a wireless information/navigation service.
  • the processor 12 retrieves data from various sensing devices and determines whether imminent movement of the vehicle is present.
  • the processor 12 sends signals to various control devices for deploying counter-measures to prevent the vehicle from moving.
  • the processor 12 may be the same processor as used by the occupant sensing system or other vehicle system. This alleviates the requirement for additional hardware and reduces cost.
  • the occupant sensing system 14 may include any device that can sense the presence of the driver in the driver seat.
  • the occupant detection system 14 generates a signal indicating whether or not the driver is seated in the driver's seat and transmits the signal to the processor 12 accordingly.
  • Such systems include, but are not limited to, weight based sensors 20 , electromagnetic spectrum-based sensing devices 22 (e.g., infrared detection sensors, lidar sensors), pressure sensors 24 , strain sensors 26 , electric sensors 28 , piezoelectric sensors 30 , safety restraint sensors 32 , vision-based devices 34 , and door actuation sensors 36 .
  • Such sensors detect a presence of the driver in the driver's seat.
  • the at least one vehicle movement indication device 16 includes one or more devices that indicate whether the vehicle is moving or whether the vehicle is free-rolling (i.e., movement is not inhibited). Such devices include but are not limited to, transmission gear sensor 40 , ignition sensor 42 , wheel speed sensor 44 , vehicle-based imaging device 46 , global positioning device (GPS) 48 , and road incline sensor 50 . Each of the devices may be used individually or in combination to determine an imminent movement of the vehicle. For example, the wheel speed sensor 44 , or the vehicle-based video camera 46 , or the GPS 48 may be used to determine whether the vehicle is actually moving by determining displacement of the vehicle over time.
  • GPS global positioning device
  • Other devices such as the transmission gear indicator 40 , the ignition sensor 42 , the road incline sensor 50 , and the emergency brake indicator 52 identify whether vehicle devices are engaged to prevent the vehicle from moving or not engaged which would allow the vehicle to freely move, if acted on by an outside force.
  • Logic may be performed by the processor 12 that analyzes a state of the various devices and determines whether imminent movement of the vehicle is likely. For example, if the driver is not detected in the driver's seat and the transmission gear indicator 40 indicates that the transmission is out of park and the road incline sensor 50 senses that the vehicle is on an incline, then the processor 12 would determine that imminent movement of the vehicle is very likely.
  • the processor 12 determines that precautions are already in place to prevent the vehicle from moving. As a result, the transmission being out of park position along with the determination of the absence of the driver in the drivers seat in cooperation with data from at least one of the other movement detection devices allows the processor 12 to determine the imminent movement status of the vehicle.
  • Vehicle movement prevention devices 18 may be actuated by the processor 12 or control signal may be transmitted from the processor 12 to a controlling device that actuates the vehicle movement prevention devices 18 .
  • Vehicle movement preventions devices 18 include, but are not limited to, braking devices 60 and gear shift devices 62 .
  • Braking devices 60 are actuated through vehicle systems that include, but are not limited to, anti-lock braking system, brake-by-wire braking systems, electronic braking system or any other system that can autonomously (i.e., without the aide of the driver) actuate the vehicle brakes.
  • Gear shift devices 62 include gearing operations that may be actuated via an autonomous gear shift system, such as electronic shifting.
  • electronic shifting the transmission gears may be autonomously shifted to engage the transmission park position for preventing movement of the vehicle.
  • FIG. 2 illustrates a block flow diagram for deterring undesired movement of a vehicle.
  • a vehicle movement prevention routine is initiated. Vehicle operating conditions of the vehicle are monitored.
  • a set amount of time e.g. 1 second
  • a driver temporarily leaving the seat may be the result of the driver leaning over to get something in another seat, or may be due to the driver temporarily propping oneself up (e.g., straightening a coat or a skirt beneath them). If the occupant sensing device does not sense the person within a predetermined period of time (e.g., 2 seconds), then the routine proceeds to step 73 ; otherwise, if the occupant sensing device does sense the driver in the driver's seat, then a return is made to step 70 to continue to monitor the vehicle operating conditions. It should be understood that if the system senses the driver of the vehicle in the driver's seat, then the driver remains in full control over the vehicle.
  • a predetermined period of time e.g. 2 seconds
  • Imminent movement as used herein is defined as actual movement of the vehicle or a likelihood of movement of the vehicle that may occur as a function of various factors that include, but are not limited to, that the vehicle transmission is not in the park position and a driver is not seated in the driver's seat.
  • Various factors may indicate that the vehicle is currently moving, such as monitoring the wheel speed sensor and sensing movement of the wheel over a respective distance in a respective amount of time, or may be determined based on displacement of scenes as captured by a vehicle video capture device, by a GPS device, or by the ignition system engages/engine running condition.
  • Other devices may identify a potential for the vehicle to move such as the vehicle being parked on an incline.
  • Various other devices, such as the state of engagement of the emergency brake may increase likelihood of the vehicle potentially moving if not engaged or may decrease the likelihood that the vehicle may move based on the emergency brake engaged. If the determination is made that the imminent movement of the vehicle is present, then the routine proceeds to block 74 , otherwise the routine proceeds to step 70 to continue monitoring vehicle operating conditions.
  • the vehicle movement prevention device may include a system wherein a group of components cooperatively function as a unit to perform the action.
  • the respective devices may include brake actuation devices wherein pressure is autonomously applied to the vehicle brakes for locking each of the wheels in place to prevent movement of the vehicle. This may be performed by ABS systems or brake-by-wire systems.
  • the respective devices may further include autonomous gear shift systems, such as electronic shifting, where the transmission automatically places the transmission into the park position. Any autonomous vehicle device/system can be used for preventing movement of the vehicle without the driver having to manually engage the brake pedal, the gear shift mechanism, or emergency brake.
  • a remote control e.g., key fob
  • the user may utilize a remote control (e.g., key fob) to actuate one of the vehicle movement prevention devices to prevent movement of the vehicle.
