  • Patent number: 9217639
    Abstract: A true north heading is determined by using gyroscopes of differing accuracy and orienting a gyroscope of a higher accuracy to a direction that is more sensitive to azimuth change (e.g., an east/west direction). A gyroscope with a lower accuracy is placed perpendicular to the gyroscope with a higher accuracy and can be oriented towards a north or south direction. The gyroscopes may be placed on a rotatable platform to properly orient the gyroscopes. The higher-accuracy gyroscope may be implemented by using multiple gyroscopes oriented in the same direction.

  • Patent number: 9216724
    Abstract: A brake maintenance indication system having a first portion determines the brake cylinder pressure and a second portion that is configured to determine the intended brake cylinder pressure based on the difference between the brake pipe pressure and the emergency reservoir pressure. The intended brake cylinder pressure is preferably determined to be 2.5 times of the difference between the brake pipe pressure and the emergency reservoir pressure. In the event of brake cylinder over-pressurization or under-pressurization, an indicator is flagged, thus identifying the presence of a problem with the braking system.

  • Patent number: 9194321
    Abstract: A system according to the principles of the present disclosure includes a starter control module, an engine speed module, and a sensor diagnostic module. The starter control module generates a starter engage signal to engage a starter of an engine. The engine speed module determines a speed of the engine based on input from at least one of a camshaft position sensor and a crankshaft position sensor. The sensor diagnostic module selectively diagnoses a fault in the at least one of the camshaft position sensor and the crankshaft position sensor based on a rate of change in the engine speed before the starter engage signal is generated.

  • Patent number: 9150204
    Abstract: A braking force control device can control braking forces of the respective wheels of a vehicle, suppresses an increase of the braking force of a first wheel that is a wheel having a relatively large slip amount in a pair of right/left wheels and increases the braking force of a second wheel that is a wheel having a relatively small slip amount. The braking force control device may suppress the increase of the braking force of the first wheel before the friction coefficient of a road surface to the first wheel reaches a peak and when the friction coefficient is in the vicinity of the peak. It is preferable to suppress the increase of the braking force of the first wheel by holding the braking force of the first wheel.

  • Patent number: 9086279
    Abstract: Methods are provided for determining the length of a path traveled by a vehicle using an onboard unit that generates a sequence of position readings and a related position quality index for each position reading. A set of consecutive position readings is extracted from the sequence. Position readings are discarded having position quality indices falling below a threshold. A set quality index is determined based on the number of position readings of the set or on the position quality indices. If the set quality index exceeds a threshold, the path length is determined based on mutual distances of consecutive position readings of the set. Otherwise, the path length is determined using a digital road map composed of road segments by associating the position readings of the set with at least one road segment, and determining the path length based on the segment length of the at least one road segment.

  • Patent number: 9031761
    Abstract: A driving assist apparatus for a vehicle is provided. The apparatus includes a determination unit that determines a state of a traffic flow in a lane in which a ego-vehicle is driving, on the basis of acceleration of the ego-vehicle and inter-vehicle distances to other vehicles around the ego-vehicle. The apparatus also includes a drive control unit that controls a motion of the ego-vehicle and is capable of switching drive control according to a determination result by the determination unit. The drive control unit switches the drive control when the determination result indicates that the state of the traffic flow is a state of a critical region which is present in a transition period from a free-flow state to a mixed-flow state. Here, the free-flow state is a state in which the probability of occurrence of traffic congestion is low, and the mixed-flow state is a state in which a braking state and an acceleration state of a vehicle are mixed.
