71 Control system for engine and transmission using two power modes US299684 1989-01-23 US4972737A 1990-11-27 Seiji Makimoto
A control system for a vehicle with an automatic transmission in which the gear ratio is automatically changed in accordance with the operating condition of the vehicle includes a control means set for at least a first range if air-fuel ratios to be determined in accordance with engine speed and a second range of air-fuel ratios for controlling the air-fuel ratio of the engine to enrich a fuel mixture more than in the first range of air-fuel ratios. A shift control system has a first shift characteristic setting means for setting a first shift characteristic, and a second shift characteristic setting means for setting a second shift characteristic such that an upshift is effected in a higher vehicle speed range than that in the first shift characteristic. A characteristic changing means selects the first shift characteristic during ordinary driving (i.e. non-power driving) and the second shift characteristic during a specific operating condition. An air-fuel ratio changing means expands the first range of air-fuel ratios toward the high-speed side of engine operation when the second shift characteristic has been selected by the characteristic changing means to narrow the second range of air-fuel ratios. Thus, when an acceleration force is demanded during ordinary driving, the vehicle is driven to gain a sufficient acceleration force, and at the same time the air-fuel ratio enrichment control is restrained to control the worsening of fuel economy.
72 Electronic control system for a motive unit US600039 1984-04-13 US4653003A 1987-03-24 Gerhard Kirstein
Components of a motive unit to be checked are connected to a control system that includes a microcomputer through branch lines. One branch line serves to provide trigger signals and test the components in the normal operating state when the parts are rotating (i.e. in the dynamic state). The other branch serves to monitor the same components for malfunctions in the stopped condition when the parts are not moving (i.e. in the static state). The other branch contains a switching network, a current/voltage source controlled by the microcomputer, and an analog-to-digital converter. There is further provided a priority control circuit over which program interrupt requests or requests for changing to an emergency program are transmitted. In the event a malfunction causes an interrupt request to be generated, the interrupt request from the priority control circuit is transmitted immediately or with a delay depending upon the priority assigned to the particular event malfunction.
73 Method of automatic gear selection in a vehicle power transmission US403614 1982-07-27 US4517646A 1985-05-14 Karl G. Magnusson; Hans V. Stahl
Method for automatic gear selection in a vehicle power transmission, said selection being catered for by a control system including an electronic unit (1) which, in response to signals representing vehicle speed and engine load, coacts with a programmable read-only memory PROM (28), in which there are stored, for each gear position, alternative speed limits for changing gear to neighboring gears and also limiting values relating to speed change and engine load for selection between said alternative speed limits. To eliminate the risk of unsuitable gear selection for heavy vehicles, e.g. in conjunction with changing gear on a hill, the invention is essentially distinguished in that during travel, data on speed change and engine load are stored in a random access memory RAM (29); that the speed value most recently stored in said RAM before the initiation of the gear selection is compared, together with values stored in said RAM and relating to speed change and engine load at a certain instant before the initiation of the speed change, with values stored in said PROM and relating to speed, speed change and engine load, respectively; that said comparison results in the choice of a certain gear; that in the electronic unit (1) there is generated an output signal representing the selected gear; and that said output signal is fed to an operative means for indicating and/or engaging the selected gear.

A shift control device is provided with a structure wherein when a driver selects a manual shift mode, an appropriate shift level is set as an initial shift level in conformity to a driver's will to have or not to have a drive-force source braking effect. When a shift lever 72 is operatively moved to an S-position to select an S-mode, depending on whether a stay time in a position “D” continuing for a certain time period or more (step S2), a shift mode switching or a manual shift mode direct-selecting is determined, and then an initial shift level is individually determined for a shift mode switching (YES in step S2) and a manual shift mode direct-selecting (NO in step S2). This determines appropriate initial shift level in conformity to the driver's will to have the drive-force source braking effect in the shift mode switching and that not to have the drive-force source braking effect in the manual shift mode direct-selecting.
79 SHIFT CONTROL APPARATUS FOR VEHICULAR CONTINUOUSLY VARIABLE TRANSMISSIONS US12526104 2008-02-14 US20100100289A1 2010-04-22 Masahiro Tawara; Shinya Toyoda; Tadashi Tamura
A shift control apparatus for vehicular continuously variable transmissions is equipped with a related value calculating portion (102) that calculates a first driving force related value in association with an automatic shift mode in which an automatic shift control portion (92) performs shift control and that calculates a second driving force related value in association with a manual shift mode in which a manual shift control portion (94) performs shift control, and a second changeover portion (108). The first driving force related value and the second driving force related value are set larger as the driving force output from an engine (12) increases. The second changeover portion makes a changeover from the manual shift mode to the automatic shift mode on the basis of a relationship between the first driving force related value and the second driving force related value.
80 Shift control apparatus and method for automatic transmission of vehicle US11797711 2007-05-07 US07695404B2 2010-04-13 Hidenori Saitoh; Masami Kondo
When an n speed prohibition command is being output from the AI shift controlling component, the AI shift control is performed even in the S mode if the vehicle speed V is lower than the reference vehicle speed Vn, whereby busy shifting can be effectively prevented when the vehicle is running on an uphill road or cornering. When the vehicle speed V is equal to or higher than the reference vehicle speed Vn, the AI shift control is cancelled, thus minimizing the possibility of a large engine brake force being applied to the vehicle despite the intention of the driver.
