Title: Method for monitoring an exhaust after treatment device
Inventor: PHILIPPE BOVI
IPC: F01N11/00
Filed: 2020-03-04
Abstract: A control unit receives temperature signals from a pair of temperature sensors (20, 22, fig 4) arranged upstream and downstream of an exhaust treatment device (16, fig 4). The control unit runs a temperature model to estimate a temperature of the exhaust treatment device, taking into account the thermal inertia of the exhaust treatment device and receiving as input an inlet temperature determined by the upstream temperature sensor. The thermal model uses a nominal inertia corrected by a correction coefficient, the correction coefficient being determined by a learning procedure on the basis of a deviation between modelled and measured outlet temperatures during a transient engine operating phase, such as at cold start. The exhaust treatment device may be a catalyst or particulate filter. An internal combustion engine (12, fig 4) comprises an exhaust system with the control unit, temperature sensors and exhaust treatment device.

Title: Reset domain control
Inventor: ARI OJA
IPC: G06F1/24
Filed: 2021-02-04
Abstract: An integrated circuit 2 has multiple reset domains 104, 106. The domains may comprise processor cores 4, 6. A first domain 104 has a register, which is read by a circuit 6 outside the domain. When a reset request 38a to a global reset controller requests a reset of the domain, the controller sends a reset warning signal 40a, waits for a predetermined delay and then sends a reset signal 34a to the domain. The reset warning signal may be sent to a local reset controller 18 of the domain. The local reset controller may terminate a bus transaction involving the register on a bus 22 outside the domain and may prevent the register being sampled from outside the domain. Circuitry in the first domain may generate the reset request. The central reset controller may send reset signals to multiple domains in response to one request based on a mask.
