  • Patent number: 10691960
    Abstract: A surrounding monitoring apparatus obtains the position of a pedestrian contained in an image captured by a camera mounted on a vehicle on the basis of the position of the pedestrian in the image, and determines, on the basis of the obtained position, whether or not the possibility of collision with the pedestrian is high. In the apparatus, an error in extracting the pedestrian position may increase temporarily. In view of this, when the magnitude of change in a position correlation value representing the position of the pedestrian per a predetermined time (position change amount) exceeds a change amount upper limit value, the apparatus modifies the position correlation value such that the position change amount becomes equal to the change amount upper limit value and determines, on the basis of the modified position correlation value, whether or not the possibility of collision with the pedestrian is high.

  • Publication number: 20190023267
    Abstract: A surroundings monitoring apparatus obtains the position of an object from a captured image of a region in a heading direction of a vehicle, and obtains a position obtainment accuracy. When the distance between the object and the vehicle becomes relatively short, the position obtainment accuracy increases. However, the distance between the object and the vehicle becomes shorter, the position obtainment accuracy may decrease. Therefore, if collision avoidance control is performed for an object selected on the basis of the position obtainment accuracy, there is a possibility that the collision avoidance control is not performed for an object which is most likely to collide with the vehicle. In view of this, the apparatus obtains, for each object, a required deceleration which is the magnitude of acceleration necessary for stoppage at a position before the object, and performs the collision avoidance control for an object which is the largest in the required deceleration.

  • Patent number: 9562482
    Abstract: A vehicle is equipped with an auxiliary that is driven by the output of an internal combustion engine and which is capable of obtaining drive force by transmitting the output of the internal combustion engine to driving wheels. If an air conditioning compressor is being driven during engine idling of the internal combustion engine, an electronic control apparatus implements output-increase control for increasing the output of the internal combustion engine in comparison to when the air conditioning compressor is not being driven. If the force applied to the accelerator pedal (Pac) is equal to or more than a prescribed value (Pth), output-reduction control for reducing the output of the internal combustion engine by initiating engine idling of the internal combustion engine, and prohibiting the drive of the air conditioning compressor, is implemented.

  • Patent number: 9199645
    Abstract: Disclosed is a vehicle control apparatus which can prevent drivability from being deteriorated. The ECU is operative to determine whether the previously depressed brake is in the “ON” or “OFF” state when the vehicle is determined as being not travelling on a bad road, the accelerator being in the “ON” state, and the brake being in the “ON” state. When the ECU is operative to determine that the previously depressed brake is in the “OFF” state, and the vehicle is in the reduced speed state, the ECU is operative to perform the reduction process of the engine output under the condition that the simultaneous depressions of the accelerator and brake pedals are held for less than 10 seconds, and the vehicle speed is 7 km/hr or more. When, on the other hand, the ECU determines that the vehicle is travelling on the bad road, the ECU is operative not to perform the reduction process.

  • Patent number: 9156462
    Abstract: A drive control apparatus for a vehicle includes: a control unit that controls drive force output from an engine in accordance with operation of an accelerator pedal; and a shift mechanism capable of selectively switching a shift position to a driving position or a non-driving position. The shift mechanism transmits the drive force to wheels when the shift position is in the driving position, and interrupts transmission of the drive force when the shift position is in the non-driving position. The control unit executes a drive force restriction process of reducing the drive force when the shift position is switched from the non-driving position to the driving position while the accelerator pedal is in an on state, and, when the switching is from a neutral position, the control unit changes a mode of reducing the drive force in accordance with a continuation time of the neutral position.

  • Patent number: 9145115
    Abstract: Disclosed is a vehicle control apparatus which can prevent the deterioration of drivability. The ECU can set a control accelerator opening degree to be converted when a control permission condition is established. The control accelerator opening degree is equal to or larger than an accelerator lower limit which is larger than an idle determination value for determining an automatic stopping of an engine by an eco-run. The control accelerator opening degree thus set can prevent the drivability from being deteriorated without the automatic stopping of the engine being caused even if the accelerator opening degree is converted to reduce the torque of the engine with the establishment of the control permission condition.

  • Patent number: 9097189
    Abstract: When a driver attempts to hurriedly start driving a stopped vehicle, for example, the driver may, without realizing it, begin operating an accelerator pedal before shifting a shift lever from a non-drive position to a drive position. In such a situation, when the shift lever is shifted from a non-drive position to a drive position while the accelerator pedal is being operated, a drive power limiting process is implemented for limiting the drive power when the drive power is output from a drive source in accordance with the amount that the accelerator is being operated. As a result, when the shift lever is shifted from a non-drive position to a drive position in the abovementioned manner, it is possible to restrict starting of the vehicle, which is caused by the transmission of drive power from the drive source to the wheels. This reduces the strange sensation experienced by the driver.

  • Patent number: 9050965
    Abstract: When an ECU determines that an accelerator is “ON” and a brake is “ON”, the ECU determines whether or not the brake previously depressed is “OFF”. When the ECU determines that the brake previously depressed is “OFF” and that the vehicle is in the reduced speed state, the vehicle control apparatus is configured to execute an engine output reduction control process under the condition that the simultaneous depressions of the accelerator and brake pedals continues for less than 10 seconds and the vehicle speed is not less than 7 km/hr. When the simultaneous depressions of the accelerator and brake pedals continues for no less than 10 seconds, the ECU is configured to make an output reduction prohibition flag “ON” and not to execute the engine output reduction control process until a predetermined time elapses.

  • Patent number: 9046044
    Abstract: Provided is a vehicle control apparatus that can prevent the deterioration of drivability. An ECU executes a reduction control when speed reduction of a vehicle is determined as a control permit condition is established, and does not execute the reduction control when the speed reduction is not determined as the condition is not established. Additionally, when determined that a vehicle behavior stabilization control that stabilizes behavior of the vehicle is being executed, the ECU determines the speed reduction of the vehicle by changing a speed reduction threshold value for determining the speed reduction. This makes it possible to adequately determine the speed reduction of the vehicle even when a drive state of the vehicle is changed by the execution of the vehicle behavior stabilization control, thereby allowing the execution and non-execution of the reduction control to be switched reflecting a driver's intention and thus preventing the drivability from being deteriorated.

  • Patent number: 8930100
    Abstract: A vehicle has a shift mechanism and a position detection device that detects an operation position of the shift mechanism. A transmission is brought to a power transmission state when an operation unit of the shift mechanism is operated to a driving position, and is brought to a power interrupt state when the operation unit is operated to a non-driving position. A driving force limitation process for reducing the driving force of an internal combustion engine is executed when it is determined that the non-driving position has been shifted to the driving position on the basis of the operation position of the operation unit as detected by the position detection device. The driving force limitation process is prohibited when it is determined that the vehicle is traveling and that the operation unit is not operated to any of the operation positions.
